A geocentric orbit or Earth orbit involves any object orbiting Planet Earth, such as the Moon or artificial satellites.
The LK (ЛК, from Лунный корабль, "Lunniy korabl", meaning "Lunar craft"; GRAU index: 11F94) was a piloted lunar lander developed in the 1960s as a part of the Soviet attempts at human exploration of the Moon. Its role was analogous to the American Apollo Lunar Module (LM). Several LK articles were flown without crew in Earth orbit, but no LK ever reached the Moon. The development of the N1 launch vehicle required for the Moon flight suffered setbacks (including several launch failures), and the first Moon landings were achieved by US astronauts. As a result, both the N1 and the LK programs were cancelled without any further development.
A low Earth orbit (LEO) is an orbit around Earth with an altitude of or less, and with an orbital period of between about 84 and 127 minutes.
