Gerasimovich (Moon)

Named after Boris Petrovich Gerasimovich - Soviet astronomer (1889-1937).

Gerasimovich is a lunar crater on the far side. 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. Nearby craters of note include Houzeau to the north and the smaller Ellerman to the southeast. (wikipedia entry)

A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
