The main component of the atmosphere is nitrogen, accounting for 78.1%; Oxygen accounts for 20.9%; Hydrogen accounts for 0.93%; There are also small amounts of carbon dioxide, helium, neon, krypton, xenon and water vapor. The air density of the atmosphere decreases with the increase of altitude. The higher the air, the thinner the air. The thickness of the atmosphere is about 1000 km, but there is no obvious boundary. The whole atmosphere shows different characteristics with different heights, which is divided into troposphere, stratosphere, mesosphere, warm layer and escape layer, and then interstellar space.

More than 500 kilometers above the ground, it is called the outer atmosphere, also called the magnetosphere. It is the outermost layer of the atmosphere and the transition zone from the atmosphere to interstellar space. There is no clear boundary outside. In general, the upper limit is low near the geomagnetic pole, and it is about 9 ~ 10 radius of the earth high above the near-magnetic equator, in other words, it is about 65,000 kilometers high. The air here is extremely thin.
