It is the star of Poseidon in the solar system: it has the strongest storm in the universe.

There are eight different planets in our solar system. They all live in orbits around the sun. However, there is a planet in orbit away from the sun called Neptune. Its diameter is the fourth largest star in the solar system, but its brightness is only 7.85.

Therefore, in the night sky, humans can't find it with the naked eye, because it is covered with dark blue fluorescence, so it is also called "Neptune".

Because it is a distant planet, humans have not explored it too much, only visited it at 1989.

Neptune has a twin brother, Uranus. There are many similarities between them. Although Venus is bigger than Neptune, its mass is bigger than Uranus. Compared with the mass of the earth, it is more than 14 times that of the earth. In Neptune's atmosphere, hydrogen is the most abundant, followed by helium and methane, and a small amount of ammonia.

Because of the existence of methane, its surface always looks blue, and its cloud temperature is about -2 18 degrees Celsius, which is one of the coldest areas in the solar system. There is also a fiery heart under the cold appearance, and its core temperature is about 7000 degrees Celsius.

According to the visit of Voyager 2, Neptune has the strongest wind in the solar system, and the maximum speed of the storm reaches 2 100 km per hour.

In addition, Neptune has a special place, that is, its Antarctic temperature (about -200 degrees Celsius) is about 10 degrees Celsius higher than the surface temperature. This temperature can release the methane gas above into space, while the methane in other areas is frozen.

Although this planet is not well known to us, maybe one day humans may set foot on its land.
