From school course We know that all the planets in our solar system vary in mass, that there are giant storms on the Sun, and that gas giants Huge hurricanes are also raging. But modern astronomy has been actively developing over the past few years, leading to mind-blowing discoveries.
1. Surface of Mars
Mars is greatly underestimated: modern astronomers are discussing the possibility that Mars may once have been home to ancient forms of bacteria or oceans liquid water. More recently, it has become known that many species of the first microbes to appear on Earth originated on Mars and only then they got to Earth with the help of asteroids.
Sometimes we see in the media some of the most mind-blowing photographs of the most strange features surface of the Red Planet, and all this increases interest in Mars as a planet with a mysterious past. In 2006, the Mars Reconnaissance Orbiter began operating in orbit around Mars, and its camera took incredible pictures of many regions of the planet.
The image below shows the trails left by huge dust devils - the Martian equivalent of a tornado. They blow away the top layer of soil, which consists mainly of iron oxide (the substance responsible for the red tint of the soil), revealing dark gray layers of basalt.
2. The missing planet
Astronomers have long noticed discrepancies in the orbits of the outer gas giants, which, in particular, contradict most of our models depicting the first years after formation solar system. There is a hypothesis that previously there was another planet in the solar system with a mass of several tens of Earth’s.
The hypothetical planet, sometimes called Tycho, was most likely ejected from the solar system billions of years ago in interstellar space, where she is doomed to rush between systems until the end of time.
This planet could be located billions of kilometers beyond the orbit of Pluto in a region that is extremely poorly illuminated by the Sun. Its orbit was elliptical, and it took millions of years to complete one revolution around the Sun. Taken together, these factors explain why such a planet would be undetectable.
3. Diamond rain on Neptune and Uranus
Besides the mystery shrouding the strange orbits of these planets, there is another: they both have magnetic poles, shifted as much as 60° away from their geological poles. One explanation for this is that the planets once collided or swallowed up another unknown planet.
Based on information about the strange tilt of Uranus and Neptune, as well as high concentration carbon in their atmospheres, astronomers believe that Neptune and Uranus have huge oceans of liquid carbon with solid diamond icebergs drifting on the waves. These planets can also rain tiny pieces of diamond.
4. The Earth is shrouded in a halo of dark matter
Dark matter is one of the deepest mysteries of modern cosmology. Astronomers know that we are missing something extremely important to decipher its properties, but we know that dark matter makes up a huge part of total mass Universe.
Now we already know something about the properties of dark matter: in particular, it serves as a kind of anchor that holds galaxies and solar systems together. Thus, dark matter also plays a role in internal work our Solar System, which is especially noticeable when observing its impact on space technology.
A phenomenon known as the flyby anomaly proves that some of our spacecraft and satellites are inexplicably changing their orbital speeds during flight to or from Earth. This indirectly proves that the Earth is shrouded in a huge halo of dark matter: if dark matter were visible in the optical range, the halo would be comparable in size to Jupiter.
5. On Titan you could attach wings to your back and fly
Titan, a satellite of Saturn, is one of the most beautiful places in the Solar System: rains of gaseous substance fall on it, and on its surface you can see a large concentration of liquid methane and ethane.
It doesn’t seem to sound too attractive for a space traveler. However, Titan is favored by the amazing combination of low gravity on its surface and low Atmosphere pressure: If the people on Titan attached artificial wings to their backs, they could fly. Of course, for now, without proper equipment, being on Titan is deadly, but what is death compared to flying?
6. Our solar system has a tail
A month ago, one of NASA's missions revealed the presence of a tail in the solar system, shaped like a four-leaf clover.
The tail, called heliotail, consists of neutral particles that cannot be seen with traditional means. Thus, to obtain correct image particles were needed special tools. Scientists had to take several separate images and then combine them together to get a complete picture.
Heliotail extends more than 13 billion km beyond its borders. distant planet, and thanks to strong winds, particles travel beyond the solar system in all directions at a speed of 1.6 million km/h.
7. The Sun's magnetic field changes slightly
In fact, the Sun is quite predictable: it follows a continuous eleven-year cycle, at certain points in which the Sun is at its peak of activity, before activity declines again, at which time the Sun reverses its polarity.
According to NASA, all signs indicate that this event will occur very soon, perhaps within the next few months - changes have already begun at the North Pole.
Of course, you shouldn’t expect fiery rain in the sky - solar activity will simply increase.
8. We are surrounded by black holes
There are several types. First, there are stellar-mass black holes - the most common type formed during the destruction of massive star. This occurs when the star no longer has the necessary hydrogen for nuclear fusion, which leads to the combustion of helium. Because of this, the star becomes unstable, which leads to one of two scenarios: compression into neutron star or collapse into a black hole.
Eventually, many of these black holes merge to form supermassive black holes, and our Galaxy, like millions of others, orbits a central supermassive black hole.
Another type of black hole, called Planck black hole, can bombard the Earth constantly. These tiny atom-like formations could theoretically be produced by collisions in a particle accelerator, where beams of protons collide at near the speed of light.
There is no reason to worry. In most cases, Planck black holes disintegrate immediately without causing any damage. Such black hole in order to absorb even one atom of matter, it takes much more time than our Universe exists, not to mention an object of such mass as the Earth.
9. Jupiter's magnetosphere could swallow the Sun
Jupiter is the most large object in the solar system, not counting, of course, the Sun: it is so huge that 1,400 Earth-sized planets could fit in it.
Jupiter's magnetosphere is the most powerful and largest magnetosphere in the Solar System, it is even stronger than that of the Sun, and could easily absorb the Sun along with its visible corona.
To make the picture a little clearer (since the sizes of the Sun and Jupiter are still difficult to compare), we note the following: if we could see the magnetosphere of Jupiter from here on Earth, it would appear larger than full moon in our sky. In addition, in some areas of Jupiter's magnetosphere the temperature is higher than on the surface of the Sun.
10. Strange life forms may exist on gas giants
Life can arise in the most incredible conditions. In particular, bacteria have recently been discovered to thrive in deep geothermal vents on the ocean floor, where temperatures are above the boiling point.
Despite this, Jupiter seems a dubious place for the origin of life. It's basically a giant cloud of gas, isn't it? Life, it would seem, simply cannot arise there, let alone develop in any way.
Perhaps this opinion is wrong. An experiment conducted in the early 1950s, known as the Miller-Urey experiment, showed that we could create organic compounds, which are the first steps for the emergence of life, through lightning and the right chemical compounds.
Given this information and the fact that Jupiter meets a number of requirements, such as the presence of water (Jupiter may have largest ocean liquid water in our solar system), methane, molecular hydrogen and ammonia, it is possible that the gas giant could be the cradle of life.
However, Jupiter has higher atmospheric pressure than any other planet in the solar system. They also blow on Jupiter strong winds, which could hypothetically facilitate the spread of the corresponding compounds. This suggests that life would take a long time to emerge under such conditions, but many believe that certain forms Ammonia-based life may thrive in the clouds upper layers atmosphere where temperature and pressure maintain water in a liquid state.
One of the supporters of this idea, Carl Sagan, believes that in the atmosphere of Jupiter there may be various shapes life: hunters, scavengers, “prey” - they can all play a role in a hypothetical the food chain Jupiter.
Our Solar System is the least mysterious part of the Universe, but that doesn't mean we know everything about it. Here are 10 facts you may not have heard.
10. Jupiter Eats Space Debris
We all know that Jupiter is a planet with a big red spot on its surface and a storm that never stops. Did you know that Jupiter is vital to the safety of the Earth? This is the largest planet and its correspondingly largest gravitational force attracts space debris, which would be extremely dangerous if it entered our orbit. Scientists have recorded a number of cases when, thanks to the gravitational force of Jupiter, space debris went beyond the solar system.
9. There are five dwarf planets in our solar system
It's amazing how different they are cosmic bodies, like "dwarf planets", the moon and full-fledged planets. Dwarf planets are fairly large celestial bodies that do not dominate their orbit to be called true planets. However, they do not orbit other planets like the Moon. Five dwarf planets include the recently demoted Pluto, Ceres, Eris, Haumea and Makemake.
8. There are not so many asteroids in the solar system
Although it has been scientifically proven that our solar system has a large asteroid belt between Jupiter and Mars, as well as small groups of asteroids, we believe the movies more. We present spaceships scurrying between asteroids. In fact, there is so much space between them that there is no need to scurry around.
7. Venus is the hottest planet
Most would think that Mercury should be the hottest because it is closest to the Sun. However, Mercury does not have an atmosphere that stores heat precisely because it is so close to the Sun. Venus is the hottest because of its dense atmosphere that traps heat. Do you want more? She rotates in opposite direction compared to most planets.
6. Pluto's status has long been questioned
Although many of us have long known that Pluto is a planet, the recent decision to deprive it of this status is not at all spontaneous. In fact, Pluto's status as a planet has been debated in astronomical academic circles for nearly thirty years. The main reason for such discussions was the tiny size of Pluto. It is one hundred and seventy times smaller than the Earth.
5. One day on Mercury is 58 Earth days
Mercury has an unusual orbital trajectory that makes its day (a full rotation) equal to almost sixty Earth days. And if you were to look at the Sun from Mercury, its orbit would make the Sun appear to move forward and backward across the sky.
4. The seasons on Uranus last twenty years
Uranus has an inclination angle of 82 degrees, making it appear to be lying on its side in orbit. Each season on the planet is equal to 20 Earth years. It is quite possible that this is the reason for such strange weather phenomena on this "littered" planet.
3. The mass of the solar system is 99% the mass of the sun
We all know that the Sun is big, VERY big, but because it is small in the sky, it is difficult for us to imagine how big it is. Here are some measurements. The Sun makes up more than 99% of the total mass of the Solar System (including planets, moons, asteroids, etc.).
2. You would weigh less on the moon
We all know that the mass of the Moon is much less than the mass of the Earth, which means that the gravitational force there is much less, more precisely six times. Who is looking for a quick weight loss program?
1. Saturn is not the only planet with rings
Despite what we were told in school, Saturn is not the only planet, which has rings made of small rocks, ice and other particles. This is simply the only planet where we can see these rings from Earth. In fact, Jupiter, Neptune and Uranus also have rings. Uranus has nine bright rings and several fainter ones. It seems ours school knowledge information about the solar system is quite scarce. We bet you would more attention would have spent in school if you had been told these ten facts.
Astrophysics - comparatively young science. But it was she who began to study interesting facts about the planets of the solar system, everything about their structure and composition. Having separated from astronomy, she studies physical composition celestial bodies.
The sky has always been the object of close attention and interest of mankind. The stars have been observed since the time of the mythical Atlantis. The structure of celestial bodies, the trajectories of their movement, the change of seasons on Earth - all this was attributed to the influence of stars. Many theories were confirmed, others were rejected. Over time it was discovered that the Earth not the only planet in our galaxy.

List of celestial bodies
Moving on to the description interesting features each, you need to list all the small and large planets of the solar system. A table indicating the position from the sun will be placed just below. Here we will limit ourselves to an alphabetical listing:
- Venus;
- Earth;
- Mars;
- Mercury;
- Neptune;
- Saturn;
- Jupiter;
- Uranus.
Attention! It is noteworthy that the top three included bodies on which, according to science fiction writers, people would eventually settle. Scientists doubt this option, but everything is subject to science fiction.
Curious facts
Everyone has seen the film “Carnival Night,” so there is no need to retell the plot. But even in terms of New Year's celebrations, which are discussed in the film, there should be a report on the topic: “Is there life on Mars?”
What happened to the lecturer and the report itself is well known to the audience. There is often information about Mars in the news.
Astronomical information also includes the fact that it rotates along the fourth trajectory, if we count from the Sun, refers to earth group etc.
Mars
It is interesting that all the names of the nearest planets are named after ancient Roman gods. Mars is the god of war ancient mythology. There is a little confusion as many consider him to be a fertility god. Both are right. The Romans considered him the god of fertility, who could both destroy and save the harvest. Then, already in ancient Greek mythology, he received the name Ares (Mars) - the god of war.
Attention! Red Planet - Mars acquired its unofficial name due to great content iron on the surface, which gives it a reddish tint. God received his formidable name in Greek mythology for the same reason. The reddish tint resembled the color of blood.
Few people know that the first month of spring is named after the god of fertility. It sounds the same in almost any language. Mars - March, Mars – March.
Mars is considered one of the most interesting planets in the solar system for children:
- The highest point on Earth three times lower than high point Mars. Mount Everest is over 8 km high. Mount Olympus (Mars) - 27 km.
- Due to weaker gravity on Mars you can jump three times higher.
- Like Earth, Mars has 4 seasons. Each lasts 6 months, and the entire a year is 687 Earth days (2 earthly years-365x2=730).
- He has his own Bermuda Triangle" Of every three satellites launched towards it, only one returns. Two disappear.
- Moons of Mars (there are two of them) revolve around it for about same speed towards each other. Because orbital radii are different, they never collide.
Venus
An inexperienced user will immediately answer that the most hot planet solar system, it is the first from the sun - Mercury. However our Earth's twin Venus will easily give him a head start. Mercury has no atmosphere, and although it 44 days heated by the Sun, it spends the same number of days cooling down (A year on Mercury is 88 days). Venus due to the presence of an atmosphere with a high content of carbon dioxide holds high temperature constantly.
Attention! Located between Mercury and Earth, Venus is almost constantly under a “greenhouse” cap. The temperature stays around 462 degrees. For comparison, lead melts at a temperature of 327 degrees.
Facts about Venus:
- She has no companions, but itself is so bright that it can cast a shadow.
- A day on it lasts more than a year - 243 earth days(year - 225).
- 3. All planets in the Solar System rotate counterclockwise . Only Venus rotates the other way.
- The wind speed on it can reach 360 km/h.
Mercury
Mercury - first planet from the Sun. Let's consider interesting information about him:
- Despite the dangerous proximity with his hot neighbor, he there are glaciers.
- Mercury boasts geysers. Because there is no oxygen on it, they consist of pure hydrogen.
- American research satellites detected presence of a small magnetic field.
- Mercury is eccentric. Its trajectory has an ellipse, the maximum diameter of which is almost twice the minimum.
- Mercury is covered in wrinkles and, since it has a minimum atmospheric thickness. As a result inner core cools down, shrinking. Therefore, his mantle was covered with wrinkles, the height of which could reach hundreds of meters.
Saturn
Saturn, despite minimal amount light and warmth, not covered by glaciers, since its main components are gases: helium and hydrogen. It is one of the ringed planets in the Solar System. Galileo, who first saw the planet, suggested that the rings were a trace of the movement of two satellites, but they rotate very quickly.
Interesting information:
- Shape of Saturn - oblate ball. This is due to the rapid rotation of the celestial body around its axis. Its diameter at the widest part is 120 thousand km, at the narrowest - 108 thousand km.
- It ranks second in the solar system in terms of the number of its satellites - 62 pieces. At the same time, there are giants larger than Mercury, and there are very small ones with a diameter of up to 5 km.
- The main decoration of the gas giant are its rings.
- Saturn 760 times more than Earth .
- Its density is second only to water.
Researchers have proposed an interesting interpretation of the last two facts when teaching children:
- If you create a bag the size of Saturn, then it would fit exactly 760 balls, the diameter of which is equal to the globe.
- If a giant bathtub comparable to its size was filled with water, then Saturn would float on the surface.
Pluto
Pluto is of particular interest.
Until the end of the twentieth century, it was considered the most the farthest planet from the Sun, but due to the discovery of the second asteroid belt beyond Neptune, in which fragments were found weighing and diameter exceeding Pluto, since the beginning of the 21st century it has been transferred to the status of dwarf planets.
An official name to designate bodies of this size has yet to be invented. At the same time, this “shard” has five of its satellites. One of them, Charon, is almost equal in its parameters to Pluto itself.
There is no planet in our system with blue sky, except for Earth and... Pluto. In addition, it is noted that there is a lot of ice on Pluto. Unlike Mercury's ice sheets, this ice is frozen water, since the planet is quite far from the main body.
Jupiter
But the most interesting planet- this is Jupiter:
- He has rings. Five of them are fragments of meteorites approaching him. Unlike Saturn's rings, they do not contain ice.
- The moons of Jupiter were named after the mistresses of the ancient Greek god after whom he was named.
- It is the most dangerous for radio and magnetic devices. Its magnetic field can damage the instruments of a ship that tries to approach it.
- The speed of Jupiter is also interesting. Days on it are only 10 hours, and year is the time during which it occurs revolution around a star, 12 years.
- The mass of Jupiter is several times greater than the weight of all other planets orbiting the Sun.
Earth
Interesting facts.
- The South Pole - Antarctica, contains almost 90% of all the ice on the globe. Almost 70% of the world's fresh water is located there.
- Longest mountain range is underwater. Its length is more than 600,000 km.
- The longest range on land is the Himalayas (over 2500 km),
- The Dead Sea is the second deepest point in the world. Its bottom located at 400 meters below ocean level.
- Scientists suggest that our celestial body used to have two moons. After a collision with him, the second one crumbled and became an asteroid belt.
- Many years ago Earth was not green-blue, as in today's photographs from space, but purple, due to large number bacteria.
These are not all the interesting facts about planet Earth. Scientists can tell hundreds of interesting, sometimes funny, pieces of information.
Gravity
The simplest interpretation of this term is attraction.
People walk along horizontal surface because she attracts. A thrown stone still falls sooner or later - gravity effect. If you are unsure on a bike, you fall - gravity again.
The solar system and gravity are interconnected. Celestial bodies have their own orbits around the star.
Without gravity, there would be no orbits. This entire swarm flying around our star would scatter in different directions.
Attraction is also manifested in the fact that all planets have round shape. Gravity depends on distance: several pieces of any substance are mutually attracted, resulting in a ball.
Table of length of day and years
It is clear from the table that the further the object is from the main luminary, the shorter the day and longer years. Which planet has the most short year? On Mercury it is only 3 earth months. Scientists have not yet been able to confirm or refute this figure, because not a single earthly telescope can constantly observe it. The proximity of the main luminary will definitely damage the optics. The data was obtained through space research vehicles.
The length of the day also depends on body diameter and the speed of its rotation. White planets of the Solar System ( earth type), whose names are presented in the first four cells of the table, have a rocky structure and a rather slow speed.
10 interesting facts about the solar system
Our solar system: Planet Uranus
Conclusion
The giant planets located beyond the asteroid belt are mostly gaseous, due to which they rotate faster. Moreover, all four have poles and an equator rotate with at different speeds . On the other hand, since they are on greater distance from the star, a complete flight around their orbit takes quite a long time.
All space objects are interesting in their own way, and each of them contains some kind of mystery. Their study is lengthy and very an entertaining process, which every year reveals to us new secrets of the Universe.
As you know, the Earth is only a small part vast universe. In this article we will tell you interesting facts about planets that you have never even heard of.
1. Despite large mass and impressive size, Saturn is the most fast planet our solar system. To make one full circle, she only needs 10 hours. This phenomenon occurs due to magnetic field"giant" and radiation around it. But it takes Saturn 29 years to fly around the Sun.
2. The most large satellite Jupiter is called Ganymede. It is even larger than the planet Mercury. The diameter of Ganymede is more than 5 thousand kilometers.
3. It’s a very big day on the planet Mercury. It is equal to 176 days on Earth. The reason for this is the low speed of the planet around its axis. A complete revolution around the Sun takes Mercury about 88 days.
4. Saturn, Jupiter and Neptune are amazing because they emit more energy than they receive from the Sun. About one and a half times - Jupiter, 2 times - Saturn and 3 times - Neptune.
5. Venus is the hottest planet in our solar system. 465 degrees Celsius - that's it average temperature on its surface. Scientists on Venus have discovered a real greenhouse effect.
6. Yourself nearby planet Mercury appears towards the Sun. Its diameter is 4878 kilometers. By the way, this is practically equal to the area Atlantic Ocean on the ground. Temperatures on Mercury are very different during the day and at night. If at night it is minus 190 degrees Celsius, then during the day it is plus 430 degrees.
7. Interesting Facts about planets also concerns Mars. This planet has a red tint. The diameter of Mars is about 7 thousand kilometers. Mars has the most large mountain(from all the planets in our solar system). This is a volcano called Olympus. Its height reaches 27 kilometers and its width is 520 kilometers. It is Olympus that scientists consider when understanding the question: “Is there life on Mars?”
7. Bailey is the largest crater on the Moon that can be seen from Earth. Its area is 26 thousand square kilometers.
8. Besides Saturn, Neptune is a giant planet. Its diameter is 50 thousand kilometers. Which is 4 times more sizes Earth.
9. On Jupiter, the largest planet in our solar system, the same weather mechanisms exist as on our planet. The atmospheric engine is the water cycle, resulting from the movement of huge air masses.
10. Saturn’s neighboring planet is Uranus. It is also larger than the Earth. Its diameter is 50,700 kilometers. Only this planet is at an angle of 98 degrees relative to the conventional vertical axis. For example, the Earth is located at an angle of 23.5 degrees.
11. In terms of time, two revolutions of Pluto are equal to three revolutions of Neptune around the Sun.
12. One of Jupiter’s satellites is called “Europe” - according to the name of a character in the mythology of antiquity.
13. Only Venus can be compared to the size of the Earth. Its diameter is 12,104 kilometers, and that of the Earth is 12,742 kilometers. The volume of the atmosphere of Venus is 96.5% composed of carbon dioxide and 3.5% - from nitrogen, water vapor, oxygen and carbon monoxide. For comparison, the atmosphere on Mars consists of 95% carbon dioxide. Venus rotates in reverse side around the Sun, that is, from east to west. After this planet our Earth is located.
14. One of the craters of Mercury is named after the writer Edgar Allan Poe.
15. The weight of the Earth is 80 times greater than the weight of the Moon.
16. On the planet Venus, everything except mountain range, named after James Maxwell, has a feminine name.
17. Pluto remains the least studied planet to date.
Our home is not a country or even a planet, but the entire solar system, infinitely interesting and vast. We still know very little about planets and other celestial bodies, but science continues to develop, and the days are not far off when the first manned spacecraft will be sent to distant gas giants. Now we can only be content with grains of knowledge...
Facts about the planets of the solar system
- It was formed about 4.57 billion years ago.
- Judging by the presence on Earth heavy metals, our solar system was formed from “recycled materials” obtained from previously existing and then exploded stars.
- About 99.86% of its total mass comes from the Sun itself (see).
- Just as the Earth revolves around the Sun, the solar system revolves around the center of the Galaxy, and it moves at a speed of 220-240 kilometers per second.
- All the other planets in the solar system could fit between the Earth and the Moon.
- Not only Saturn has rings, but also all the other giant planets - Jupiter, Uranus and Neptune.
- Among all the planets of the solar system, Uranus and Neptune are the least studied, and Mars has been studied the most (see).
- The hottest planet in the system is Venus. It is further from the Sun than Mercury, but due to its incredibly dense atmosphere, which near the surface becomes almost liquid due to the monstrous pressure, the temperature near its surface exceeds 460 degrees. This is higher than the melting point of lead. There are also rains of sulfuric acid, but due to the heat they do not reach the surface, evaporating in the atmosphere.
- Europa, one of Jupiter's moons, has more water than Earth.
- Auroras occur not only on Earth, but also on some other planets of the solar system.
- A day on Mars lasts almost as long as on Earth - only 37 minutes longer.
- Among all the other planets in the solar system, it is Mars that is most similar to Earth, but it is cold and almost devoid of an atmosphere. However, in hot summer days the temperature at its equator rises above 0 degrees.
- Only three celestial bodies in the Solar System, not counting the gas giants, have a dense atmosphere - Earth, Venus and Titan, a satellite of Saturn (see).
- Mercury's core occupies a larger percentage total volume than any other planet. Scientists believe that the once monstrous collision literally tore off the planetary crust.
- Mars is home to Valles Marineris, the most gigantic canyon complexes in the solar system.
- Some asteroids also have rings, like Saturn. For example, at Chariklo.
- The most large satellite in the solar system is Ganymede, one of the satellites of Jupiter (see).
- Voyager 1, launched in 1977, was the first spacecraft that have gone beyond the solar system.
- For the entire time that elapsed from the moment of its discovery until the moment it was deprived of its status as a planet, Pluto did not make a single full turn around the Sun.
- Many scientists believe that somewhere in the Kuiper belt, beyond Pluto and other minor planets, there is another planet, probably a gas giant. This is indicated by a number of indirect signs.
- In the Oort cloud surrounding the Solar System, there are, according to various estimates, 2-3 trillion comets with a nucleus more than 1 km in diameter.
- Jupiter protects our Earth from asteroids and meteorites - its powerful gravity attracts them, and they burn up in its atmosphere without reaching our planet.
- The official wind speed record once recorded on Earth was 408 km/h. And on Neptune the wind blows at a speed of 2000-2200 km/h (see).
- The size of Venus is almost identical to the size of the Earth, as is its mass and the force of gravity on its surface. However, this is where the similarities end.
- There was once water on Venus, but it evaporated due to the monstrous heat, and the solar wind blew it out of the upper atmosphere.
- The radiation emitted by the Sun is deadly, and only the atmosphere and the Earth’s magnetic field protect us from it.
- The largest space object in the Solar System is International space station. And at the same time the most expensive, and in the entire history of mankind at once (see).
- Most cold planet Solar system is Uranus. The temperature in its atmosphere is about -224 degrees.
- In addition to the Earth, rivers, seas and lakes exist, at least on Saturn's moon Titan. They were photographed by the Cassini probe during its landing on Titan. True, it is not water that flows in them, but liquid methane and ethane.
- The highest peak in the solar system relative to the local analogue of “sea level” is the Olympus volcano on Mars - 22 kilometers. For comparison, Everest, highest peak The height of the earth does not even reach 9 kilometers. But there is a mountain that reaches as much as 26 kilometers from the bottom to the top. It's called Reyavilvia, and it's located on the asteroid Vesta.
- Among all the planets in the solar system, only Venus rotates clockwise. All others are counterclockwise, except for Uranus. Due to the axis tilt angle of 90 degrees, Uranus rotates as if lying on its side.
- The most large model The solar system, on a scale of 1 to 20 million, was recreated in Sweden. It is scattered over a space with a diameter of 950 kilometers.
- Storms and hurricanes rage not only on Earth, but also on other planets of the solar system. On Mars, dust storms sometimes last for 3-4 months, and on Jupiter, a monstrous atmospheric vortex, the Great Red Spot, a hurricane the size of Earth, has existed for several centuries.
- On Saturn there are clouds of regular hexagonal shape. What it is is a mystery (see).
- There are volcanoes on both Earth and Venus, but the most geologically active celestial body in the solar system is Io, a satellite of Jupiter. Its surface is literally dotted with volcanoes, and it is constantly flooded with lava flows.
