Murchison (Moon)

Named after Sir Roderick Impey Murchison - Scottish geologist (1792-1871).

Murchison is a lunar crater on the north edge of the Sinus Medii, named in honour of the geologist Sir Roderick Murchison. It shares a section of rim with the crater Pallas. To the southeast on the mare is the circular crater Chladni, and to the northeast is Ukert. Farther to the east is the prominent Triesnecker. (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.
