Prinz (Moon)

Named after Wilhelm Prinz - German-Belgian astronomer (1857-1910).

Prinz is the lava-flooded remains of a lunar crater on the Oceanus Procellarum. The formation lies to the southwest of the prominent crater Aristarchus. To the north-northeast is the flooded crater Krieger. The rim is the most intact in its northeastern half, while a large gap exists in the southern end of the crater 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.
