Gardner (Moon)

Named after Irvine Clifton Gardner - American physicist (1889-1972).

Gardner is a small lunar impact crater in the northeast part. It lies due east of the crater Vitruvius, in a section of rough terrain north of the Mare Tranquillitatis. This crater was previously designated Vitruvius A before being given its present name by the IAU. To the northeast is the larger crater Maraldi. (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.
