Hausen is a large lunar impact crater that lies along the south-southwestern limb of the Moon.

[1] The visibility of this crater is significantly affected by libration effects, although even under the very best of conditions it is viewed nearly from on edge.

The inner wall is terraced at the northern and southern ends, and is more irregular along the eastern and western flanks.

The rim along the east and southeast flanks displays slumping, producing a sharp edge.

It is not significantly eroded or overlaid by craters, with only a single small craterlet along the southwest rim.
