Neptune's atmosphere has the highest wind speed in the solar system, which should be driven by the heat flow inside it. Its weather feature is an extremely violent storm system, and the wind speed reaches supersonic speed, which is about 2100 km/h/h. In the equatorial region, the typical wind speed can reach about 1200km/h[24].

The temperature at the top of Neptune's atmosphere is only-218 c (55k).

From the top to the center, the atmosphere contains about 10% to 20%, and the upper atmosphere is mainly composed of 80% hydrogen and 19% helium. The contents of methane, ammonia and water increase with the decrease of height. The temperature at the bottom of the inner atmosphere is higher and denser, and then it gradually mixes with the superheated liquid in the planetary mantle. The pressure in Neptune's core is millions of times the atmospheric pressure on the earth's surface.

It is located outside the solar system, and the solar light it receives is 1000 times weaker than that on the earth.
