Jeans is a lunar impact crater, on the southeastern limb of the Moon, with its majority lying on the far side. A favorable libration can bring the entire crater into view, but even then the details observable from Earth are very limited as the crater is viewed rather "edge-on".

Jeans is located nearly midway between the much larger walled plain Lyot on the near side and the crater Chamberlin 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.

Satellite craters[edit]

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.
