- Roche (crater)
lunar crater data
eponym=Édouard A. Roche
Roche is a large crater on the far side of the
Moonfrom the Earth. The prominent Pauli crater lies across the southern rim of Roche, and the outer of Pauli covers a portion of Roche's interior floor. To the north-northwest of Roche is the Eötvös crater, and just to the west-northwest lies Rosseland crater.
The western rim of Roche has been somewhat distorted and straightened. The rim as a whole is worn and eroded, with multiple tiny craterlets marking the surface. The satellite crater 'Roche B' lies across the northeastern inner wall.
The interior floor of Roche is relatively level, but is also marked by several small and tiny craterlets. A grouping of these craters lies near the mid-point. Just to the northwest of this grouping is a bright patch of high
albedomaterial. Sections of the floor along the north-northwestern side have a lower albedothan elsewhere, usually an indication of basaltic- lavaflows similar to what created the lunar mares. The extend of this patch may actually be larger, but covered with higher albedo"ejecta".
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Roche crater.
