Ross is a lunar crater that is located in the northwest part of the Mare Tranquillitatis. It lies south-southwest of the crater Plinius, and northwest of the lava-flooded Maclear.

This crater has a generally circular shape, but is not quite symmetrical. The inner walls slope down to a base of slumped material, before joining a relatively level interior floor. There is a low ridge to the west of the crater midpoint.

This should not be confused with the similarly named crater Rosse, which is located farther to the northeast.

Satellite craters[edit]

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Ross.
