Cockcroft (Moon)

Named after Sir John Douglas Cockcroft - British nuclear physicist; Nobel laureate (1897-1967).

Cockcroft is a lunar crater that is situated on the far side from the Earth, so that it has only be observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed. The rim of this crater is worn and eroded from subsequent impacts. The satellite crater Cockroft N is intruding into the south-southwestern 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.
