Fridman (crater)
Encyclopedia
Fridman is the remains of a lunar
crater
on the far side of the Moon
. It lies due south of the huge walled plain Hertzsprung
, and is attached to the northeastern rim of the crater Ioffe
.
This crater lies in the southern part of the ejecta blanket that encircles Hertzsprung, and in the west-northwestern part of the huge ejecta blanket surrounding the Mare Orientale
impact basin. The outer rim of this crater is heavily damaged, with a number of smaller craters lying across the sides. The most intact portion of the rim is along the southeastern side.
The southwestern interior floor is partly overlaid by the outer rampart of Ioffe. The northern floor is marked by several small craters, while the southeastern floor is impacted by a number of tiny craterlets.
This crater is called Friedmann in some sources.
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...

Hertzsprung (crater)
Hertzsprung is an enormous lunar crater that is located on the far side of the Moon, beyond the western limb. In dimension, this formation is larger than several of the lunar mare areas on the near side. It lies in the northwestern fringe of the blast radius of the Mare Orientale impact basin...

Ioffe (crater)
Ioffe is a lunar impact crater on the far side of the Moon. It lies to the south of the walled plain Hertzsprung, and is attached to the southwestern outer rim of Fridman. Only a short stretch of terrain separates Ioffe from Belopol'skiy to the southeast....

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...
