McDonald (Moon)

Named after William Johnson McDonald - American benefactor (1844-1926) and Thomas Logie McDonald - Scottish selenographer (1901-1973).

McDonald is a small lunar impact crater located in the central Mare Imbrium. This crater is a cup-shaped feature with a circular rim, and has not been significantly eroded. It lies to the southeast of the slightly larger crater Carlini, in an isolated part of the mare. (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.
