Hausen (crater)
Encyclopedia
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 walled plain Bailly
. To the northeast is the crater Pingré
on the near side, and to the north is the Arrhenius
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.

The Moon is Earth's only known natural satellite,There are a number of near-Earth asteroids including 3753 Cruithne that are co-orbital with Earth: their orbits bring them close to Earth for periods of time but then alter in the long term . These are quasi-satellites and not true moons. For more...

Libration
In astronomy, libration is an oscillating motion of orbiting bodies relative to each other, notably including the motion of the Moon relative to Earth, or of Trojan asteroids relative to planets.-Lunar libration:...

Bailly (crater)
Bailly is a lunar impact crater that is located near the south-west limb of the Moon. The oblique viewing angle gives the crater a foreshortened appearance, and the location near the limb can limit visibility due to libration...

Pingré is a lunar impact crater that is located near the southwest limb of the Moon, beyond the large crater Phocylides. It lies to the northwest of the huge walled basin Bailly, and to the east of the smaller Graff...

Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge...

- Hausen A — See ChappeChappe (crater)Chappe is a lunar impact crater that lies along the southwestern limb of the Moon. It is nearly attached to the northern limb of the walled plain Hausen, and an equal distance from the crater Pilâtre. To the north-northwest is Blanchard....
. - Hausen B — See PilâtrePilâtre (crater)Pilâtre is a lunar crater near the southwestern limb of the Moon. It is located just to the north-northwest of the much larger walled plain Hausen.
