Ukert (Moon)

Named after Friedrich August Ukert - German historian, humanitarian (1780-1851).

Ukert is a lunar impact crater that lies on a strip of rugged ground. It is located to the north-northwest of the crater Triesnecker and northeast of the crater pair of Pallas and Murchison. The outer rim of this crater is not quite circular, with outward bulges to the north and the east. The interior floor is irregular in places, with a central ridge running from crater midpoint down to the southern wall. (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.
