1. Mercury. Mercury is the closest planet to the Sun and the smallest planet. Due to its proximity to the Sun, Mercury's surface temperature is extremely high and there is almost no atmosphere, which makes Mercury's environment unusually harsh. Mercury's surface has many impact craters, the largest of which is called the Calorie Basin, which is up to 1,300 kilometers in diameter.
2. Venus. Venus is Earth's sister planet, but its environment is very different from Earth's. Venus has a very thick atmosphere, with a surface temperature of up to 460, making it the hottest planet in the solar system. In addition, there are many volcanoes and lava flows on the surface of Venus, the most famous of which is Mount Etna, which reaches a height of 11,220 meters.
3. Mars. Mars is one of the planets outside of Earth that is most likely to host life. Mars' atmosphere is very thin and has a low surface temperature, but it's still enough to sustain some water ice. The surface of Mars has many canyons, volcanoes, and impact craters, the most famous of which is Mariner's Valley, which is one of the largest canyon systems in the solar system.
4. Jupiter. Jupiter is the largest planet in the solar system, with a mass of 2 times the mass of the rest of the planets in the solar system combined5 times. Jupiter's atmosphere is very thick and has a large number of storms and vortices on its surface, the most famous of which is the Great Red Spot, which is a huge vortex storm that has been going on for hundreds of years. Jupiter also has a very large number of moons, the most famous of which are the Galilean moons.
5. Saturn. Saturn is one of the most beautiful planets in the solar system, and its appearance consists of many bright stripes and spots. Saturn's atmosphere is also very dense and consists mainly of hydrogen and helium. Saturn also has a very large number of moons, the most famous of which is Titan, which is one of the largest moons in the solar system.
6. Uranus.
Uranus is an ice giant with an atmosphere filled with hydrogen and helium, as well as large amounts of methane and ammonia. Uranus' surface temperature is low, reaching minus 220, but it's still enough to sustain some water ice. Uranus's axis of rotation is inclined, almost lying in an orbital orbit to rotate.
7. Neptune.
Neptune is one of the farthest planets in the solar system, and its atmosphere is filled with hydrogen and helium, along with large amounts of methane and ammonia. Neptune's surface temperature is low, reaching minus 214, but it's still enough to sustain some water ice. Neptune has a very strong magnetic field, even stronger than Earth's.
8. Haumea.
Haumea is a Kuiper Belt object, and it is one of the largest known Kuiper Belt objects. The name of Hauma is derived from the god of pregnancy in ancient Greek mythology. It has a very strange shape, it looks like a peanut, with very prominent ends and a concave part in the middle.
IX. Sedna.
Sedna is an asteroid with a very elliptical orbit, with perihelion near Neptune's orbit and aphelion outside the Kuiper Belt. Sedna's appearance takes on a reddish hue, which may be related to the large amount of sulfur-containing substances it contains. At present, there is relatively little information about Sedna.
10. Genesis.
Tronis is an asteroid with a very elliptical orbit, with perihelion near Neptune's orbit and aphelion outside the Kuiper belt. The appearance of Tronis has a reddish hue, which may be related to the large amount of sulfur-containing material it contains. At present, there is still relatively little information about Tron God.
