Eponym Moritz L. G. Wichmann

Wichmann is a bowl-shaped lunar impact crater. It is located in the southern half of Oceanus Procellarum on a low plateau formed from a wrinkle ridge. No notable craters are nearby, to the northwest is Flamsteed, further north is Encke, further east is Euclides and south is the smaller Scheele.

There is a small mountain chain to the north that curves away to the west that is designated Wichmann R; this is most likely the rim of a worn crater that was buried by the lava flow forming the mare. Additional low mountains lie to the south of the plateau on which Wichmann is situated. These mountains partly touch and surround the wrinkly ridge known as Dorsa Ewing.
