Gregory (lunar crater)
Encyclopedia
Gregory is a lunar
crater
on the far side of the Moon
. It is located to the southeast of the crater Ibn Firnas
, and north-northeast of Bečvář
. About one crater diameter to the north is the smaller Morozov
.
This is a worn and eroded crater formation. The northern rim is degraded due to impacts. Attached to the exterior of the southwest is Gregory Q, a satellite crater about the same size as Gregory. Within the interior is the remains of a small crater rim along the northwestern inner wall.
To the east of Gregory and leading away to the southeast is a crater chain designated Catena Gregory.

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...
