Capella & Isidorus

Capella (49 km) is bisected by a deep valley, Vallis Capella from the North to the South East rim and extends beyond the frame of the image. The valley appears to be a crater chain and was probably formed by debris ejected from the Mare Nectaris impact. The flooded crater to the RHS is Isidorus (42 km). The internal crater is Isidorus A (10 km).
