Nasmyth is a lunar crater located near the southwest limb of the Moon. It is attached to the southeast rim of the Wargentin crater, and the southern half is overlain by the larger Phocylides crater. The rim of Nasmyth is worn and impacted in several locations by craterlets, most notably 'Nasmyth D' which lies across the north rim. The floor has been flooded by lava flows in the past, making the surface relatively flat and the rim low. There is no central peak within the crater, but the floor is impacted by some small craterlets.
Satellite craters
By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Nasmyth crater.
