Wilhelm (crater)
Wilhelm IV |
Wilhelm is a
This crater is of the type traditionally termed a walled plain. It has a heavily eroded outer rim that is overlain by several smaller craters. Among these are Wilhelm A and Wilhelm K across the southwest rim, and Wilhelm B just to the northwest along the western rim. Wilhelm C intrudes into the north-northeast rim, and Wilhelm D is attached to the northeast outer rim. There is an outward protrusion in the southern rim that extends to contact Montanari.
The interior floor of Wilhelm is relatively level, with a rougher area to the northeast. The remainder is flat and almost featureless except for a few tiny craterlets.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Wilhelm.
