Baco is a lunar impact crater that lies in the rugged southern highlands on the near side of the Moon. The rim and inner wall has been eroded and worn by countless minor impacts since the original formation of the crater. As a result, any terraces have been worn smooth and the rim is overlaid by several tiny craterlets. The interior floor is nearly flat, with no characteristic central peak at the midpoint and no small craters of significance.
There are several minor craters located in the surrounding terrain, including the satellite craters Baco A just to the south and Baco B to the northwest. Further to the north is the crater Breislak, and equally distant to the northeast is Ideler. Further to the west is Cuvier, while Asclepi lies to the southeast.
Baco is a Celtic god, invoked by Gauls and attested on inscriptions found in the areas of Chalon-sur-Saône and Eauze. His name indicates that he was probably a boar-god, of whom many are recorded in the Celtic world. Note also Old Irishbacc ‘bend, hook, corner’.
