It would seem that a lot is known about the solar system to everyone who at least sometimes opened an astronomy textbook at school. But in fact, our galaxy is fraught with a huge variety of secrets and secrets, and new facts about the solar system that become known to scientists can surprise even the most sophisticated experts in astronomy.
1. Rotational speed 220-240 km / s
Everything moves in space. The solar system revolves around the center of the Galaxy at a speed of 220-240 km / s, and it takes about 240 million years to complete one period of revolution.
2. Solar eclipses
Solar eclipses can be observed from anywhere in the solar system. But the Earth is the only place where you can admire a total solar eclipse.

3. The mass of the Sun is 99.86% of the mass Cc
As you know, the Sun is much larger than any planet in our system. Few people think about it, but in fact, the mass of the Sun is about 99.86% of the total mass of the Solar System.
4. Wind speed up to 2100 km / h
On Earth, the maximum wind speed was recorded on the Australian island of Barrow and was 408 km / h. And the strongest winds in the solar system blow on Neptune: up to 2100 km / h.
5. Chemical composition
Recently, scientists have developed a new model of the chemical composition of the early solar system. According to this theory, about half of the water that currently exists on Earth originated from interstellar ice during the formation of the Sun.
6. Water in Ss
Over the past couple of decades, scientists have established that some planets and their satellites in the solar system have water in different states. However, the Earth is the only place in the solar system where water can be present in all three states: solid, liquid and vapor.
7. "Dead Twin"
Of all the planets in the solar system, Venus is considered the twin of the Earth. Despite the fact that conditions on its surface are generally unsuitable for human life (for example, only the temperature is 464 ° C), it has approximately the same size and orbit with the Earth.
8. Neutrinos
In the XX century, a stable neutral elementary particle, neutrino, was discovered. To describe its size figuratively, we will give the following comparison: if an atom were the size of the solar system, then a neutrino would be the size of a golf ball.
9. To -224 ° C
The coldest planetary atmosphere in the solar system is on Uranus. Here the temperature drops to -224 ° C.
10. Highest mountain in SS
The highest mountain peak on Earth is Everest (Chomolungma), which is 8,848 m high. And the highest mountain in the solar system is on Mars. Here the height of Mount Olympus is about 22 km.
11. Largest model
Sweden has the largest model of the solar system in the world. It is made on a scale of 1:20 million and stretches for 950 km.
12. Three leaders
Uranus is the third largest planet in the solar system. The first largest is Jupiter and the second is Saturn.
13. The biggest storms
Mars also has the largest dust storms in the solar system. They often last for several months and can cover the entire planet.
14. Orbital speed of the Earth
The earth moves in orbit at a speed of about 108,000 km / h.
15. Volcanoes of Venus
According to various estimates, there are from 1,000 to 1,500 volcanoes on Earth. And most of them are in the solar system on Venus - more than 1,600.
16. Originally from the cloud
The solar system is 4.57 billion years old. It was then that it formed from a cloud of gas and dust.
17. Solar gravity
As you know, the Sun has a much stronger gravity. A person who weighs 68 kg on Earth would weigh 1,905 kg on the Sun.
18. Lunar gravity
Now let's move closer to our planet. The same person weighing 68 kg would weigh 11 kg on the moon.
19. Gravitational effects of "invisibility"
Scientists believe there is a ninth planet in the solar system far beyond Pluto's orbit, which is about 10 times the size of Earth. It has not yet been discovered, and its existence is assumed due to the gravitational effects that it has on other objects.
