Grave (Moon)

Named after Dmitry Aleksandrovich Grave - Soviet mathematician (1863-1939) and Ivan Platonovich Grave - Soviet engineer (1874-1960).

Grave is a lunar crater that lies in the northern interior floor of the huge walled plain Gagarin, on the far side. It is located about 10 kilometers to the east-northeast of the larger crater Isaev, which covers the northwestern part of Gagarin's interior. Like many lunar craters, Grave has undergone some erosion due to subsequent impacts. There are small craters across the east and southwestern sides of the circular rim. (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.
