Cavendish est un cratère de 56 Km et profond de 2350 m situé au Sud-ouest de la lune et au Sud-ouest du cratère plus grand Mersenius (85 Km, 2300 m). La muraille de Cavendish est érodé et porte Cavendish E (24 Km) au travers du mur Sud-ouest. Cavendish A (10 Km) est lui au travers du mur  Nord-est. Sur le fond inondé on note, un piton central et une paire de cratères, pas très élevés, qui sont joints aux murs Est et Ouest.

Cavendish is a lunar crater that is located in the southwest part of the Moon, to the southwest of the larger Mersenius crater. It lies between the smaller craters Henry to the west-northwest and De Gasparis to the east-southeast.

The rim of Cavendish is heavily worn and the crater 'Cavendish E' lies across the southwest rim. The smaller 'Cavendish A' is intruding into the northeast rim. On the flood are a pair of low-rimmed craters that are joined at the rims and span most of the central Cavendish crater floor from east to west.

A rille from the Rimae de Gasparis reaches the eastern rim of Cavendish.
