Michelson (Moon)

Named after Albert Abraham Michelson - German-American physicist; Nobel laureate (1852-1931).

Michelson is a crater on the far side. It lies along the northeastern outer rim of the huge walled plain Hertzsprung, and to the southwest of the crater Kolhörster. This is a heavily eroded crater formation with multiple impacts along the rim edge and within the interior. The rim is roughly circular, but has been rendered uneven due to these smaller craters.

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.
