Geological Chronicle
Located near the western limb of the Moon, Vasco da Gama is a lunar impact crater with a diameter of 93.52 kilometers. Named for the Portuguese explorer, it lies due south of Dalton and south of the walled plain Einstein. The somewhat smaller crater Bohr is attached to its southwestern rim.
The northern and southern sections of the rim have been heavily eroded by impacts, while the western and eastern rims remain more intact. Satellite crater Vasco da Gama S intrudes into the southeastern rim, with Vasco da Gama T positioned just to its southwest and Vasco da Gama B near the northeastern rim. Near the midpoint of the interior rises a low central massif.
The interior floor of satellite crater Vasco da Gama R contains a system of rilles designated the Rimae Vasco da Gama.
