Rosse is a bowl-shaped lunar impact crater located in the southern part of Mare Nectaris. To the southwest is the large, flooded crater Fracastorius, other nearby prominent craters are a little distant including Beaumont to the west, Bohnenberger nearly to the east along with Montes Pyrenaeus (Lunar Pyrenes) and further north Daguerre.
The interior of the crater has a higher albedo than the surrounding lunar mare, making it readily visible. While it lacks a ray system of its own, rays from distant Tycho cross it. Low ridges in the mare lie between this crater and Fracastorius to the southwest.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Rosse.
