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.
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.

Büsching is a lunar impact crater that is located in the crater-covered southern highlands of the Moon. It was named after German geographer Anton F. Büsching. The similar-sized crater Buch is located adjacent to its southwestern rim, and further to the southwest lies Maurolycus.
Chamberlin is a lunar impact crater that is located on the far side of the Moon, just past the southeastern limb. It lies to the southeast of the crater Jeans, and Moulton is attached to the southeastern rim of Chamberlin. This crater is located in a part of the lunar surface that has undergone resurfacing of crater interiors, producing dark-hued crater floors.
Brianchon is a lunar impact crater that is located along the northwestern limb of the Moon. Due to its location, from the Earth the crater is seen from the edge and its visibility is somewhat affected by libration. Thus for a more detailed view, the crater must be viewed from orbit.
Bjerknes is a lunar impact crater that is located in the southern hemisphere on the rugged far side of the Moon. The crater lies behind the southeastern limb, and beyond the region that is sometimes brought into sight through libration. Thus this crater can not be viewed from Earth, and has only been seen from orbit. Nearby named craters are Clark to the east, and Pogson to the south-southwest.
C. Mayer is a lunar impact crater that is located at the northern edge of the Mare Frigoris, due north of the prominent crater Aristoteles. Also to the south, but only a third as distant, is the smaller crater Sheepshanks. Due east of C. Mayer is the flooded crater Kane.
Riemann is a lunar impact crater that is located near the northeastern limb of the Moon, and can just be observed edge-on when libration effects bring it into sight. It lies to the east-northeast of the large walled plain Gauss. To the southeast, beyond sight on the far side, is the crater Vestine.
Chebyshev is a large lunar impact crater that lies in the southern hemisphere on the far side of the Moon. The somewhat smaller crater Langmuir is intruding into the east-southeastern rim of Chebyshev, forming a chain of large craters with Brouwer on Langmuir's eastern rim.
Clairaut is a lunar impact crater that is located in the rugged southern highlands of the Moon's near side. It lies directly to the south of the crater Maurolycus and southeast of Barocius. Just to the southwest is Cuvier.
Chapman is a lunar impact crater that lies just beyond the northwest rim of the Moon, on the far side as seen from the Earth. It lies to the northeast of the crater Rynin, and southward of the large walled plain Poczobutt.
Curie is a large lunar impact crater, much of which lies on the far side of the Moon as seen from the Earth. The western rim projects into the near side of the Moon, as defined by the selenographic coordinate system. However the visibility of this formation depends on the effects of libration, so that it can be brought fully into view or completely hidden depending on the orientation of the Moon. When visible, however, it is seen nearly from the side, limiting the amount of detail that can be observed.
Fraunhofer is a lunar impact crater that is located just to the south-southwest of the walled plain Furnerius, in the southeastern part of the Moon. This crater appears foreshortened when viewed from the Earth, and is actually nearly circular.
Wilson is a lunar impact crater that lies in the southern part of the Moon's near side, to the southwest of the large walled plain Clavius. It is nearly attached to the southeastern rim of the slightly larger crater Kircher. Almost due east lies Klaproth, another walled plain.
Short is a lunar impact crater that is located in the southern regions of the Moon, on the near side. It lies just to the south of the larger, prominent crater Moretus, and northeast of Newton.
Ricco is a lunar impact crater. It is located in the northern part of the Moon's far side. This crater overlies the southeastern rim of the larger crater Milankovic. Less than one crater diameter to the southwest is Karpinskiy, while to the southeast is Roberts.
Douglass is a lunar impact crater on the far side of the Moon. It lies to the southwest of the crater Frost and south-southwest of the large walled plain Landau.
Donner is a lunar impact crater on the far side of the Moon. It is located just to the northeast of the Mare Australe, behind the southeastern limb of the Moon. During favorable librations this part of the lunar surface can be brought into view of the Earth, but the site is viewed from the edge and so not much detail can be seen.
Finsen is a lunar impact crater that is located in the southern hemisphere, on the Moon's far side. It is attached to the southeastern exterior of the walled plain Leibnitz, and the ejecta from Finsen covers the southeastern part of Leibnitz's interior floor. To the southwest of Finsen is another walled plain, Von Kármán, partly overlain by Leibnitz.
FitzGerald is a large lunar impact crater on the far side of the Moon. It lies to the west-southwest of the crater Cockcroft, and about two crater diameters to the northeast of Morse.
Fridman is the remains of a lunar impact crater on the far side of the Moon. It lies due south of the huge walled plain Hertzsprung, and is attached to the northeastern rim of the crater Ioffe.
Michelson is a crater on the far side of the Moon. It lies along the northeastern outer rim of the huge walled plain Hertzsprung, and to the southwest of the crater Kolhörster.
