OCR: FACT FILE SATELLITES IN geostationary orbit fly at an altitude of 36,000 km (22,400 miles) above the Earth's equator. At this great altitude, a satellite orbits the Earth in the same time that it takes the Earth to rotate, so the satellite remains above a fixed spot on the Earth's equator at all times. Polar-orbit altitude is much lower and varies from 600 km (375 miles) to 1,600 km (1,000 miles).
