Obruchev (crater)
Encyclopedia
Obruchev is a disintegrating lunar
crater
that lies along the southern shore of Mare Ingenii
, on the far side of the Moon
. Less than three crater diameters to the south of Obruchev is the crater Chrétien
, and about the same distance to the southeast lies Oresme
.
The outer rim of this crater has been heavily damaged and now forms an irregular, rugged ring about the interior. The crater partly overlies the satellite crater Obruchev M to the south, and there is a pair of smaller craters along the western rim and inner wall. The interior of Obruchev has some uneven edges, but it is relatively level and featureless nearer the center.
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...

Mare Ingenii
Mare Ingenii is one of the few lunar mare features on the far side of the Moon. The mare sits in the Ingenii basin. This basin material is of the Pre-Nectarian epoch. The mare material located in Ingenii and the surrounding craters is of the Upper Imbrian epoch...

Chrétien (crater)
Chrétien is a lunar crater that is located in the southern hemisphere on the far side of the Moon from the Earth. It lies due south of the Mare Ingenii, one of the few maria on the Moon's far side...

Oresme (crater)
Oresme is a crater on the Moon's far side. It lies just to the west-northwest of the larger Von Kármán. To the southwest of Oresme is Chrétien, and to the northwest is the Mare Ingenii...
