Paschen is a lunar crater on the far side of the Moon. The relatively large satellite crater 'Paschen M' partly overlays the southern rim of Paschen, and the nearly form a merged pair with only a section of irregular terrain along their common border. The smaller but well-formed crater 'Paschen S' lies across the southwest rim of Paschen. As a result, most of the southern rim of Paschen is now gone.
The remainder of the rim is not in much better condition. It is worn and eroded, with multiple small craterlets along the edge and inner wall. Most of the rim structure has been worn away by subsequent impacts and deposits of ejecta, and now forms a rounded dip into the curving interior. A small chain of craters cuts across the rim and inner wall to the west-northwest. There are several small craterlets in the southeastern part of the floor.
Paschen lies to the east of the larger Galois walled-plain, and to the southwest of the huge Hertzsprung impact basin. About a half crater diameter to the northeast of Paschen is Wan-Hoo crater. Further to the north-northwest lies Sechenov crater.
[edit] Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Paschen crater.
