Named after Catherine Wolfe Bruce - American philanthropist, astronomy patron (1816-1900).
Bruce is a small lunar impact crater located in the Sinus Medii. It lies to the west-northwest of the irregular crater Rhaeticus, and is about 33 km to the west of the even smaller Blagg. This feature is circular and cup-shaped, with no notable impacts overlaying the rim or interior. The interior has a generally higher albedo than the surrounding terrain, but there is a band of darker material cross the midpoint of the crater from west to east. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On the Moon they are named after deceased scientists, polar explorers, astronauts or cosmonauts.
