The thermosphere is a rarefied portion of the atmosphere, lying in a spherical region between 55 and 300 mi (90 and 500 km) above the Earth's surface, where the temperature increases dramatically with altitude. Many satellites orbit in the upper thermosphere, and even though it is very low in density, the drag on these satellites exerted by collisions with thermospheric atoms and molecules eventually brings them down to burn up in the atmosphere.
