Crommelin (lunar crater)
Encyclopedia
Crommelin is an ancient lunar
crater
that is located in the vicinity of the south pole of the Moon
, on the far side. It lies to the north of the large crater Zeeman
, and to the east-northeast of Numerov
.
This formation has been almost completely worn away by subsequent impacts, leaving little more than a crater-riddled depression in the surface. There is an equally-worn crater lying across the northern rim, and Crommelin X is attached to the outward-bulging northwest perimeter. The largest of the craterlets within the interior form a pair near the southern rim. There is a slight central peak, consisting of little more than a low rise in the surface.
Moon
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...

Zeeman (crater)
Zeeman is a lunar impact crater located on the far side of the Moon near its south pole. It is not directly visible from the Earth. To the northwest of Zeeman lies the crater Numerov. Southeast of the rim is the crater Ashbrook....

Numerov (crater)
Numerov is a lunar impact crater that is located on the Moon's far side, deep in the southern hemisphere. It is attached to the larger and younger crater Antoniadi to the west, and the outer rampart of Antoniadi overlies the inner wall and part of the western interior floor of Numerov...
