Somerville (crater)

Somerville is a lunar impact crater that lies along the eastern edge of the Mare Fecunditatis. It is located to the southwest of the prominent crater Langrenus and northeast of the binary crater pair of Goclenius and Gutenberg.

The outer rim of Somerville is heavily worn and eroded. Several small craterlets lie along the rim edge and inner walls. The satellite crater Somerville A is attached to the exterior of the southeast rim. The interior floor is relatively level and featureless, with no central peak.

Somerville's name honors Mary Somerville, a Scottish science writer and polymath.
