Jeans is a lunar impact crater, on the southeastern limb of the Moon, with its majority lying on the far side.
It has a heavily worn and rounded outer rim, and several impacts lie along the southern and southeastern edge and inner wall.
The most prominent of these intersecting craters are Jeans G across the eastern rim.
The interior floor of the main crater has been resurfaced by basaltic lava, leaving a dark level surface marked only by a few tiny craterlets.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Jeans.
