Aepinus (Moon)

Named after Franz Maria Ulrich Theodor Hoch Aepinus - German-Russian astronomer (1724-1802).

Aepinus is a small lunar impact crater located along the northern lunar limb, close to the north pole. To the south east is the prominent crater Hermite. This crater was unnamed until it was given a name along with 18 other craters by the IAU on January 22, 2009. (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.
