Answer: It is called the thermosphere because temperatures can reach up to 1,500 degrees Celsius (2,732 degrees Fahrenheit). However, despite the high temperatures, the pressure is very low, so satellites don't suffer heat damage. Many satellites orbit within the thermosphere and changes in the density of (the very, very thin) air at orbital altitudes, brought on by heating and expansion of the thermosphere, generates a drag force on satellites.
