Lunar Phosphere

The lunar thermosphere (sometimes called the exosphere) is a very thin, outermost layer of the Moon's atmosphere. It consists of sparse particles—like helium, neon, and other gases—that are so spread out they rarely collide. Because of the Moon's weak gravity and lack of a substantial atmosphere, these particles can escape into space. This layer is extremely thin, unlike Earth's thick atmosphere, and its properties are influenced by solar radiation and the solar wind, making it a dynamic but delicate environment around the lunar surface.
