Paschen (crater)
Paschen is a lunar impact crater that is located on the far side of the Moon, behind the eastern limb. It lies to the south of the larger crater Freundlich, and northeast of Bok.
Paschen is a relatively well-formed crater with a sharp, somewhat uneven outer rim. The inner walls display some terracing and slumping, particularly along the eastern side. The interior floor is relatively level, and is marked only by a few tiny craterlets. There is a slight central peak near the midpoint of the floor.
The crater is named after German physicist Friedrich Paschen.
