Eponym Mikhail V. Shuleykin

Shuleykin is a small lunar impact crater that lies to the south of Mare Orientale, within the ring-shaped Montes Rook. It is located just on the far side of the Moon, but this area can be viewed from the Earth during periods of favorable libration and lighting, although it can only be seen from the edge.

Lunar craters

Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.

Impact crater Circular depression on a solid astronomical body formed by a hypervelocity impact of a smaller object

An impact crater is an approximately circular depression in the surface of a planet, moon, or other solid body in the Solar System or elsewhere, formed by the hypervelocity impact of a smaller body. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters range from small, simple, bowl-shaped depressions to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.

Mare Orientale Lunar mare on the western border of the near side and far side of the Moon

Mare Orientale is a lunar mare. It is located on the western border of the near side and far side of the Moon, and is difficult to see from an Earthbound perspective. Images from spacecraft have revealed it to be one of the most striking large scale lunar features, resembling a target ring bullseye.

This crater was formed following the Orientale impact event, and so is younger. It has a circular, sharp-edged rim and inner walls that slope down to the small interior floor. It has not been noticeably eroded by subsequent impacts.

Baade (crater) lunar crater

Baade is a lunar impact crater that is located near the southwest limb of the Moon on the near side, to the southwest of the enormous Mare Orientale impact basin. The area to the east of this crater forms the junction between the 280-km-long Vallis Bouvard to the north and the narrower, 160-km-long Vallis Baade to the south-southeast. Both valleys radiate away from the impact basin to the north.

Shaler (crater) Lunar impact crater

Shaler is a lunar impact crater that lies on the southeast interior edge of the Montes Cordillera mountain ring that surrounds the immense Mare Orientale formation. It is located near the southwest limb of the Moon on the near side, and so is viewed nearly from on edge from the Earth. Just to the northwest of the crater is the slightly smaller crater Wright.

Blackett (crater) lunar crater

Blackett is a lunar impact crater that lies on the far side of the Moon, behind the southwest limb. It lies beyond the southeast outer ring of the immense Mare Orientale basin. The formation of that major feature has left Blackett deeply marked with ridge features trending from the northwest. Much of the crater has been shaped by the ejecta from Mare Orientale, particularly along the western half of the crater.

Drude (crater) lunar crater

Drude is a lunar impact crater that lies on the far side of the Moon, in the rugged Montes Cordillera range that forms the outer ring around the Mare Orientale impact basin. It is located just behind the west-southwest limb, and this area is sometimes brought into sight from Earth during favorable librations. However, even at such times, the crater is viewed from the edge and little detail can be seen.

Lallemand (crater) lunar crater

Lallemand is a small lunar impact crater that lies near the western limb of the Moon, in a region where the visibility is affected by libration effects. Because of its location, when viewed from the Earth the crater is viewed nearly from the side, limiting the amount of detail that can be seen. It lies in the northeast part of a mountain range named the Montes Rook that forms a ring around the enormous Mare Orientale impact basin. To the northeast is the Lacus Autumni and to the northwest lies the Lacus Veris, both forming small lunar maria along the sides of the range.

Chant (crater) lunar crater

Chant is a lunar impact crater that is located on the far side of the Moon, behind the southwest limb as seen from the Earth. It lies within the southwestern part of the blanket of ejecta surrounding the Mare Orientale, beyond the Montes Cordillera mountain ring. To the west-northwest is the large walled plain Blackett. Southward is the crater Mendel.

Chadwick (crater) lunar crater

Chadwick is a lunar impact crater that lies on the far side of the Moon's surface, just beyond the southwestern limb. It is located to the northwest of the crater De Roy, and was previously designated De Roy X before being given its current name by the IAU. This region of the lunar surface lies at the southern end of the ejecta blanket that surrounds the Mare Orientale impact basin.

Couder (crater) lunar crater

Couder is a small lunar impact crater that is located just behind the western limb of the Moon, in a region of the surface that is brought into view during favorable librations. It lies on the inner foothills of the Montes Cordillera, a ring-shaped mountain range that surrounds the Mare Orientale impact basin.

Eichstadt (crater) impact crater

Eichstadt is a lunar impact crater that is located in the eastern section of the Montes Cordillera range that encircles the Mare Orientale impact basin. It lies toward the southwestern limb of the Moon, and so appears oblong when viewed from the Earth due to foreshortening. Over 200 kilometers to the east of Eichstadt are the craters Darwin and Lamarck, and to the south is Krasnov.

Chalonge (crater) lunar crater

Chalonge is a lunar impact crater that is located on the far side of the Moon. It lies to the southwest of the larger crater Lewis, in the outer skirt of ejecta that surrounds the Mare Orientale impact basin. To the southeast are the Montes Cordillera, a ring of mountains that encircle the Mare Orientale formation.

Steklov (crater) lunar crater

Steklov is a lunar impact crater on the far side of the Moon, past the southwestern limb. It lies in the outer skirt of ejecta from the Mare Orientale impact basin, just to the southwest of the Montes Cordillera ring of mountains. About four crater diameters to the southwest is the slightly smaller crater Chant.

Fényi (crater) lunar crater

Fényi is a small lunar crater on the far side of the Moon. It lies near the southern edge of the huge, braided skirt of ejecta that surrounds the Orientale impact Basin to the north. Less than two crater diameters to the southwest is the much larger crater Mendel.

To the north is the crater Leuschner.

Guthnick (crater) lunar crater

Guthnick is a lunar impact crater that lies on the far side of the Moon's surface from the Earth. However, it is located in the part of the far side that is sometimes brought into sight of the Earth due to libration, although it can only be seen at a low angle and during favorable lighting conditions. Guthnick is situated in the southern portion of the huge skirt of ejecta that surrounds the Mare Orientale impact basin. Less than a crater diameter to the northwest is the slightly larger crater Rydberg. To the south-southwest is the small Andersson.
