Lunar orbit

(重定向自Lunar Orbit Insertion)
The Moon from lunar orbit, with planet Earth rising over the horizon, taken on the Apollo 8 mission on December 24, 1968.

In astronomy, lunar orbit (also known as a Selenocentric orbit) refers to the orbit of an object around the Moon.

As used in the space program, this refers not to the orbit of the Moon about the Earth, but to orbits by various manned or unmanned spacecraft around the Moon. The altitude at apoapsis (point farthest from the surface) for a lunar orbit is known as apolune, apocynthion or aposelene, while the periapsis (point closest to the surface) is known as perilune, pericynthion or periselene.
