Gerasimovich (crater)
Encyclopedia
Gerasimovich is a lunar
crater
on the far side of the Moon
. It lies beyond the western limb, to the west-northwest of the immense Mare Orientale
impact basin. The outer blanket of ejecta from this impact reaches nearly to the rim of Gerasimovich. Nearby craters of note include Houzeau
to the north and the smaller Ellerman
to the southeast.
The outer rim of this crater is worn and eroded, with a perimeter that has been modified and reshaped by nearby impacts. The much younger crater Gerasimovich D lies across the northeastern rim, and lies near the center of a poorly organized blanket of higher albedo
deposits. Just to the west-southwest of the outer rim is the young, sharp-rimmed crater Gerasimoch R. The interior floor of Gerasimovich is irregular near the edges, and is marked by several small craterlets.
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...

Impact crater
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body...

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...

Houzeau (crater)
Houzeau is a lunar crater on the far side of the Moon. It is located to the northwest of the Mare Orientale impact basin, and ejecta from that event has fallen across this crater rim and its interior. To the south of Houzeau lies the crater Gerasimovich, and one crater diameter to the west is...

Ellerman (crater)
Ellerman is a lunar crater on the far side of the Moon. It lies within the outer blanket of ejecta that surrounds the Mare Orientale impact basin, and is located to the west of the Montes Cordillera mountain range...

Albedo , or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it...
