Abul Wáfa is an impact crater located near the lunar equator on the far side of the Moon, named after the Persian mathematician and astronomer Abul Wafa. To the east are the crater pair Ctesibius and Heron. In the north are two craters named Katchalsky and Viviani, in the northeast lies the larger crater King, and to the southwest is Vesalius.

The perimeter of this crater somewhat resembles a rounded diamond shape. The rim and inner walls are rounded from impact erosion, and have lost some definition. There are ledges around most of the inner wall that may have once been terraces or slumped piles of scree.

A small but notable crater lies on the inner surface of the north rim of Abul Wáfa, and there is a small crater formation attached to the exterior southwest wall. The outer rim is relatively free of impacts, and the interior floor is marked only by a few small craterlets.

The southern rim is not far from the lunar equator but its satellite crater Abul Wáfa Q has a part crossed by the equator.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Abul Wáfa.
