Eponym	Boris Gerasimovich

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.

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 Gerasimovich crater.
