The interior of this crater has been resurfaced by basaltic lava, leaving the floor flat, shallow, and nearly featureless with just a few very small sub-craters. There is no central peak at the midpoint. The outer rim remains circular and only slightly worn.

Prior to being named by the International Astronomical Union in 1976, this crater was identified as Langrenus F.^[1]
