Rydberg is a lunar impact crater that is located on the far side of the Moon, just past the southwestern limb. It lies due south of the Mare Orientale, in the outer skirt of ejecta that surrounds the Orientale impact feature. Just to the southeast is the Guthnick crater.
This is a little-eroded crater formation with a relatively sharp edge. The inner walls do not have much terracing, although slumped piles of talus lies along the base. At the mid-point of the interior is a central ridge, with a low spur that runs halfway toward the southern inner wall.
This feature was named after the Swedish physicist Johannes Rydberg.
