Zöllner is a lunar impact crater located to the west of Sinus Asperitatis. To the north is the smaller crater Alfraganus and to the northwest lies the oval-shaped Taylor. Southeast of Zöllner is the smaller crater Kant.
The rim of Zöllner forms an irregular oval, with the formation being longer in a north–south direction. The wall is low and worn, with a distorted, crater-like depression attached to the southeast of the rim. The narrow floor still retains a central peak.
The Apollo 16 landing site is located about 80 kilometers west-southwest of the crater rim.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Zöllner.
