Vil'ev (Moon)

Named after Mikhail Vil'ev - Russian astronomer (1893-1919).

Vil'ev is an eroded lunar crater on the far side. It lies to the west of the much larger crater Chaplygin, and to the north of Marconi. Just to the northeast is the small crater pair of van den Bos and Tamm. Slightly farther to the west is the larger crater pair of Pannekoek and Dellinger. (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.
