Named after Rupert Wildt - German-American astronomer (1905-1976).
Wildt is a small lunar impact crater that is located near the eastern limb. The nearest named crater is Condorcet to the west-northwest. Wildt was previously designated Condorcet K before being named by the IAU. The crater is circular and bowl-shaped, with a small floor at the midpoint of the sloping interior walls. (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.
