Explanation:

A low Earth orbit (LEO) is an Earth-centred orbit with an altitude of 2,000 km (1,200 mi) or less (approximately one-third of the radius of Earth),or with at least 11.25 periods per day (an orbital period of 128 minutes or less) and an eccentricity less than 0.25.Most of the artificial objects in outer space are in LEO.
