Rupes

Rupes is the Latin word for 'cliff'. It is used in planetary geology to refer to escarpments on other worlds. As of January 2013, the IAU had named 62 such features in the Solar System, on Mercury (17), Venus (7), the Moon (8), Mars (23), the asteroids Vesta (2) and Lutetia (2), and Uranus's satellites Miranda (2) and Titania (1).
