Bruce is a small lunar impact crater located in the Sinus Medii. It lies to the west-northwest of the irregular Rhaeticus crater. Less than forty kilometers to the south-southeast is the original point of the selenographic coordinate system. From the floor of this crater the Earth always appears at the zenith. Both the Surveyor 4 and Surveyor 6 probes landed about 50 km to the west-southwest.
