Low Earth Orbit

Low Earth Orbit - orbit is one in which the objects, such as satellites, are below the intermediate circular orbit and substantially below the orbit geostacionária but usually between 350 and 1400 km above the surface of the Earth. The orbits lower than this are not stable, and will be dragging atmospheric. The satellites in a low Earth orbit traveling at about 27400 km / h (8 km / s), which represents a revolution of about 90 minutes.
