Eponym Jesse Ramsden

Ramsden is a lunar impact crater located on the western stretch of the Palus Epidemiarum. To the east-southeast is the crater Capuanus, to the north lies Dunthorne, and to the west is Lepaute.


The floor of the crater has been flooded with lava, and contains several small impact craters. The rim is somewhat oval and irregular in outline, with depressions at the north and south walls. It has a slight rampart, but lacks terraces, a central peak, or a ray system.


The crater lies directly across a rille system named the Rimae Ramsden. These span an area 130 kilometers across, sprawling over the western Palus Epidemiarum. A branch reaches northwest to the Mare Nubium, passing between the craters Campanus and Mercator.
