Lunar orbit

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, from names or epithets of the moon goddess.

Low Lunar orbit (LLO)—orbits below altitude—are of particular interest in exploration of the moon, but suffer from gravitational perturbation effects that make most unstable, and leave only a few orbital inclinations possible for indefinite frozen orbits, useful for long-term stays in LLO.

If all goes well, we should be back in lunar orbit in less than four days.

Beneficiated pieces of comet stuff were, as a rule, set on trajectories that took them from the Kuiper Belt into Lunar orbit, there to be refined and sent down.
