Alfraganus (crater)
Crater on the Moon / From Wikipedia, the free encyclopedia
Alfraganus is a small lunar impact crater that lies in the rugged highland region to the southwest of the Mare Tranquillitatis. It is named after the Arab Muslim astronomer Alfraganus.[1] Northwest of Alfraganus is the crater Delambre, and to the south is the irregular Zöllner. The rim of Alfraganus is circular and retains a sharp edge that has not received a significant amount of wear due to subsequent impacts. The interior floor is roughly half the diameter of the crater rim.
