The exosphere is the outermost layer of Earth's atmosphere, extending from about 600 kilometers (373 miles) above sea level to approximately 10,000 kilometers (6,200 miles). It is characterized by extremely low density and pressure, where particles are so sparse that they can travel hundreds of kilometers without colliding with one another. This layer is primarily composed of hydrogen and helium, and it gradually transitions into outer space. Satellites orbit within this region, taking advantage of the minimal atmospheric drag.
