The thermosphere begins at a distance of approximately 53-56 miles above the earth's surface and extends to between 311 and 621 miles from the earth, where the exosphere begins and extends into space. Just as in the stratosphere, the temperature in the thermosphere increases as the distance from earth becomes greater.
