What is "minnaert"

Minnaert is a large lunar crater that is located on the far side of the Moon, deep in the southern hemisphere. It is partly overlain along the southeastern side by the larger and younger crater Antoniadi. To the west-northwest lies Lyman.

Nearly half the crater is overlain by the rim, outer rampart, and ejecta from Antoniadi. The remaining rim is worn and eroded, with a number of small craterlets along the edge and inner wall. The western interior floor is relatively level, but is marked by ejecta and secondary cratering from Antoniadi. If the crater ever possessed a central ridge, it may now be buried.
