What are the gases in the exosphere layer?

The exosphere, the outermost layer of Earth's atmosphere, primarily consists of hydrogen and helium, along with trace amounts of other gases like carbon dioxide, oxygen, and neon. Due to its extremely thin atmosphere, particles in the exosphere are so sparse that they can travel long distances without colliding with one another. This layer extends from approximately 600 kilometers (about 370 miles) above the Earth's surface to around 10,000 kilometers (about 6,200 miles).
