Lyot is a large lunar crater that is located along the southeastern limb of the Moon. It lies within the irregular and patchy lunar mare named Mare Australe, and to the south of Hamilton crater. Due to its location, this formation is viewed at a low angle from the Earth, and visibility is affected by libration.
The interior floor of this crater has been resurfaced by lava, leaving a dark interior with an albedo that matches the surrounding mare. The outer rim is low and heavily worn, with a perimeter that forms a somewhat distorted circle. The southwest part of the floor and rim is marked by several small, bowl-shaped craters. There is also the remains of a ghost-crater to the east of the crater mid-point.

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 Lyot crater.
