Fridman is the remains of a lunar crater on the far side of the Moon. It lies due south of the huge Hertzsprung walled-plain, and is attached to the northeastern rim of Ioffe crater.
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 Loffe crater. 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.
[edit] Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Fridmann crater.
