Stark (Moon)

Named after Johannes Stark - German physicist; Nobel laureate (1874-1957).

Stark is a lunar crater on the far side. It lies to the southeast of the prominent crater Tsiolkovskiy, and north of Subbotin. This is a heavily eroded crater with a jumbled outer rim and uneven interior. The pair of slightly smaller satellite craters Stark Y and Stark V are attached to the northwest and western exterior respectively, creating a triple-crater formation. (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.
