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

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 (crater) Lunar impact crater

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 (lunar crater) Lunar impact crater

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 (crater) Lunar impact crater

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 (lunar crater)

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 (crater) Impact crater

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 (crater)

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 (crater) Lunar impact crater

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 (crater) Lunar impact crater

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.

Inghirami (crater) Lunar impact crater

Inghirami is a lunar impact crater that is located toward the southwestern limb of the Moon. It lies to the southwest of the large walled plain Schickard. Northwest of Inghirami is the wide Vallis Inghirami, a wide, straight valley that is radial to the Mare Orientale impact basin. The valley has a length of about 140 kilometers and ends at the northern edge of the crater.

Curie (lunar crater) Lunar impact crater

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 (crater) Lunar impact crater

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.

Douglass (lunar crater) Lunar impact crater

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.

Delporte (crater)

Delporte is a lunar impact crater on the far side of the Moon. It overlies part of the northwestern rim of the huge walled plain Fermi, and the crater Litke is nearly attached to the southeastern rim. The crater is named after Eugène Joseph Delporte.

Donner (crater) Lunar impact crater

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.

Edison (crater)

Edison is a lunar impact crater on the far side of the Moon. It is located just behind the north-northeastern limb of the Moon, a region that is sometimes brought into sight from Earth during favorable librations. However even at such times not much detail can be discerned, and the crater is better observed by orbiting spacecraft.

Finsen (crater)

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.

Fridman (crater)

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.

Raspletin (crater)

Raspletin is a lunar impact crater that is located along the southeastern inner edge of the much larger walled plain Gagarin, on the far side of the Moon.

McNally (crater)

McNally is a crater that is located to the north-northwest of the much larger crater Fersman, on the far side of Moon. This is a worn crater with a rounded rim edge that is marked by many tiny impacts. Smaller, cup-shaped impacts cut through the rim along the southeastern and northern edges. There is a small craterlet along the base of the southeastern inner wall. The interior floor is otherwise relatively featureless. The crater is named after the Jesuit astronomer and Catholic priest Paul A. McNally.

Michelson (crater)

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.
