Grachev (crater)
Encyclopedia
Grachev is a lunar
impact crater
on the far side of the Moon
. It lies to the northwest of the Mare Orientale
impact basin, in the outer skirt of ejecta surrounding the Montes Cordillera
mountain ring. Passing along the southwestern edge of Grachev is the Catena Michelson
, a valley-like formation composed of a linear chain of small craters. This feature is radial to the Mare Orientale basin. To the north is the crater Leuschner
.
This crater has only a slightly eroded outer rim, with a small outward protrusion along the northern side. The interior floor is relatively featureless, with a small rise near the mid-point.
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 Orientale
Mare Orientale is one of the most striking large scale lunar features, resembling a target ring bull's-eye. Located on the extreme western edge of the lunar nearside, this impact basin is difficult to see from an Earthbound perspective.Material from this basin was not sampled by the Apollo program...

Montes Cordillera
Montes Cordillera is a mountain range on the Moon. This feature forms the outer wall of peaks that surround the Mare Orientale impact basin, the inner ring being formed by the Montes Rook...

Leuschner (crater)
Leuschner is a lunar impact crater that is located on the Moon's far side, to the northwest of the Montes Cordillera. It lies to the north of the crater Grachev, in the outer skirt of ejecta surrounding the Mare Orientale impact basin. This is a circular crater with a rim that has only been lightly...
