The outer rim of this crater has become worn due to minor impacts, leaving the features rounded and irregular. The wall is nearly disintegrated in the southeast, and is overlain by a small crater along the eastern rim. The rim is also low and slumped to the northwest. The interior floor is relatively level, but marked by several small craters, which may be secondaries from Hausen or a more distal crater. These craters occur near the midpoint of the floor where a central peak may once have existed.
