Meitner is an impact crater on the far side of the Moon, behind the eastern limb.

The small satellite crater Meitner C lies across the rim and inner wall to the northeast.

The interior floor of Meitner is relatively level, with a small craterlet just to the southwest of the midpoint and another along the northwest inner wall.

Apollo 8, the first crewed mission to orbit the Moon, happened to fly directly over Meitner (among many other craters) and obtained high-resolution photographs of the interior.

[2] By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Meitner.
