Geological Chronicle
Lying beyond the southeastern limb on the Moon's far side, Lamb is a 103.55-kilometer crater situated within the irregular mare region named Mare Australe. Located just to the east of the crater Jenner, the feature consists of outer ramparts and rough terrain nearly enclosed by lava-flooded sections of the mare.
The crater has a slender inner wall and an interior floor resurfaced by basaltic lava. Its rim is somewhat worn and irregular, but retains a generally circular shape and is not overlaid by any smaller craters of significance. The interior floor is marked only by a multitude of tiny craters and a small, unnamed crater in the south-southeastern section. To the east of Lamb lies Lamb G, a somewhat smaller, lava-flooded formation.
The crater is named after Sir Horace Lamb, a British mathematician and physicist.
