Ross is a lunar crater that is located in the northwest part of the Mare Tranquillitatis. It lies south-southwest of Plinius crater, and northwest of the lava-flooded Maclear crater. 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 located to the west of the crater mid-point. This should not be confused with the Rosse crater, which is located further to the northeast.
Satellite craters
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 Ross crater.
