There are 8,000 satellites orbiting Earth. With limited premium parking spaces, de-orbiting is not always an option.
Use the orbital dynamics map to see why satellites are placed in different orbits. Then use the satellite locator from NASA to identify the spy satellites that fly polar orbits at 100 miles above the Earth and the communications satellites that fly at 35,000 miles away.
