Hausen (crater)
Hausen is a large lunar impact crater that lies along the south-southwestern limb of the Moon. The visibility of this crater is significantly affected by libration effects, although even under the best of conditions it is viewed nearly from on edge. It lies along the western edge of the immense Bailly walled-plain. To the northeast is Pingré crater on the near side, and to the north is the Arrhenius crater just on the far side of the lunar limb. The rim of this crater is generally circular, with an outward bulge to the south-southeast. 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. The interior floor is generally level, with a few sites of rough terrain. There is a complex formation of central peaks offset somewhat to the east of the mid-point. This formation extends further in the north-south direction and consists of several ridges separated by valleys. There is a lower range of hills just to the southeast of this range and a small cluster of hills to the south.
