Montes Rook [SEP] located on astronomical body
Montes Rook
Montes Rook is a ring-shaped mountain range that lies along the western limb of the Moon, crossing over to the far side. It completely encircles the Mare Orientale, and forms part of a massive impact basin feature. This range in turn is encircled by the larger Montes Cordillera, which is separated from the Montes Rook by a rugged, ring-shaped plain.
The Montes Rook is actually a double-ring formation, sometimes divided into the outer Rook and the inner Rook, having respective diameters
wider at the southern end. The interior floor is rough, small and uneven, with no impacts of significance. There is a small central ridge.
Nicholson is located in the Montes Rook, a ring-shaped mountain formation that encircles the immense Mare Orientale feature. It lies to the northwest of Pettit.
