Communications and TV-broadcasting satellites generally orbit at 22,300 miles, which is called the geostationary orbit. This is because at this altitude, the satellites take exactly a day to get around the ... equator—because, meanwhile, the Earth spins around once a day too Other kinds of satellites can orbit as low as about 150 miles, and others operate at intermediate altitudes. An ...
