Amazing and unbelievable facts about the solar system
Our home is not a country or even a planet, but the entire solar system, infinitely interesting and immense. We still know very little about planets and other celestial bodies, but science continues to develop, and the days when the first manned ships will go to distant gas giants are not far away. Now we can only settle for bits of knowledge. Facts about the Solar System..
It was formed about 4.57 billion years ago.
Judging by the presence of heavy metals on Earth,
our solar system was formed from “recyclable materials” obtained from pre-existing stars and then exploded.
About 99.86% of its total mass falls into the Sun itself.
Just as the Earth rotates around the Sun, the Solar System rotates around the center of the Galaxy and moves at a speed of 220-240 kilometers per second.
Between the Moon and the Earth would fit all the other planets in the entire solar system.

Not only does Saturn have rings,
but also all other giant planets – Jupiter, Uranus and Neptune.
Among all the planets in the entire solar system,
Uranus and Neptune are the least studied, and Mars is the most studied (see curiosities about Mars).
The hottest of the system planets is Venus.
It is farther from the Sun than Mercury, but due to the incredibly dense atmosphere near the surface, which becomes almost liquid due to monstrous pressure, the temperature near its surface exceeds 460 degrees. That’s higher than the lead melting point. And it also rains from sulfuric acid, but because of the heat they do not reach the surface, evaporating into the atmosphere.
One of Jupiter’s moons,
Europa, contains more water than the planet.
Auroras occur not only on Earth,
but also on some other solar system planets.
A day on Mars lasts almost the same as on Earth
– just 37 minutes longer.

Among all the other planets in the entire solar system, Mars is what most resembles Earth,
but it is cold and almost devoid of atmosphere. The temperature at its equator does, however, soar above 0 degrees on warm summer days.
Only three celestial planets in the solar system have a substantial atmosphere, not to mention gas giants.
– Earth, Venus and Titan, Saturn’s satellite (see interesting facts about Titan).
Mercury’s core occupies a higher percentage of the total volume than any other planet.
Scientists believe the once monstrous collision literally tore the planetary crust off.
Mars is home to the Mariner Valleys,
the biggest canyon complexes in the solar system.
Some asteroids also have rings,
such as Saturn. For example, Chariklo.
The largest satellite in solar system is Ganymede,
one of Jupiter’s satellites (see curiosities about the satellites of the planets).
Launched in 1977, Voyager 1 became the first spacecraft to leave the solar system.
Pluto, for all the time it has spent from the time of its discovery
to the time of depriving it of planet status, has not made a single complete revolution around the Sun.
Many scientists believe that somewhere in the Kuiper belt,
in addition to Pluto and other smaller planets, there is another planet, probably a gas giant. This is indicated by a series of indirect signals.

In the Oort cloud surrounding the solar system,
there are, by various estimates, 2-3 trillion comets with a nucleus of more than 1 km in diameter.
Jupiter protects our Earth from asteroids and meteorites –
its powerful gravity attracts them, and they burn in its atmosphere without hitting 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 interesting facts about Neptune).
The size of Venus is almost identical to the size of the Earth,
as well as its mass and the force of gravity on its surface. However, the similarities stop there.
There was once water on Venus,
but it evaporated due to monstrous heat, and the solar wind expelled it from the upper atmosphere.
The radiation emitted by the Sun is deadly,
and only the earth’s atmosphere and magnetic field protect us from it.
The largest space object in the solar system is the International Space Station.
And at the same time the most expensive and in the whole history of mankind at the same time (see interesting facts about the ISS).
The coldest planet in the solar system is Uranus.
Its atmosphere has a temperature of roughly -224 degrees.

Beyond Earth, there are rivers, seas and lakes, at least on Saturn’s moon Titan.
They were photographed by the Cassini probe during the landing on Titan. It is true that it is not water that flows into them, but methane and ethane liquids.
The highest peak of the solar system compared to the local analogue of “sea level” is the Olympus volcano on Mars –
22 kilometers. For comparison, Everest, the highest peak on Earth, does not reach even 9 kilometers high. But there’s a mountain that reaches 16 miles from the foot to the top. It is called Reyasilvia and is located on the asteroid Vesta.
Among all the planets in the solar system, only Venus rotates clockwise.
All others are counter clockwise except Uranus. Due to the 90 degree tilt angle, Uranus rotates as if lying on its side.
The largest model of the solar system, on a scale of 1 to 20 million, was recreated in Sweden.
It is spread over a space with a diameter of 950 kilometers.
Storms and hurricanes ravage not only the Earth, but also other planets in the solar system.
On Mars, dust storms sometimes last 3 to 4 months, and on Jupiter for several centuries there has been a monstrous atmospheric vortex, the Great Red Spot, an Earth-sized hurricane.
There are regular hexagonal clouds on Saturn.
There are volcanoes on both Earth and Venus,
Io, a satellite of Jupiter, however, is the solar system body that experiences the highest geological activity. Its surface is literally dotted with volcanoes and is constantly flooded by lava flows.
