LEO

Low Earth orbit

Orbit around Earth with an altitude between 160 and 2,000 kilometres (99 and 1,243 mi)

A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never more than about one-third of the radius of Earth.
