Schlesinger is a lunar impact crater on the far side of the Moon. The crater Esnault-Pelterie overlies the western part of the rim and the outer rampart of that crater has covered about half the interior floor, leaving a crescent-shaped feature. To the south-southwest of Schlesinger is the crater Von Zeipel and to the southeast lies Quetelet.

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.

Moon Earths natural satellite

Earth's Moon is an astronomical body that orbits the planet and acts as its only permanent natural satellite. It is the fifth-largest satellite in the Solar System, and the largest among planetary satellites relative to the size of the planet that it orbits. The Moon is, after Jupiter's satellite Io, the second-densest satellite in the Solar System among those whose densities are known.

In addition to the overlapping Esnault-Pelterie, the rim of Schlesinger is overlain by the satellite crater Schlesinger M along the southern rim and a small crater along the northern rim. The remaining rim is heavily worn and the features have been rounded. Only about half the interior floor remains uncovered, and this is relatively level and marked only by a few small 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 Schlesinger.

Barrow (crater) lunar impact crater

Barrow is an old lunar impact crater that is located near the northern limb of the Moon. It lies between the crater Goldschmidt to the northwest and the irregular formation Meton to the northeast. To the southwest is W. Bond.

Fizeau (crater) lunar crater

Fizeau is a prominent lunar impact crater that is located on the far side of the Moon, in the southern hemisphere. Nearby craters of note include Minkowski to the west-northwest, and Eijkman to the southwest.

Büsching (crater) 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 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.

Bhabha (crater) lunar crater

Bhabha is a lunar impact crater that is located in the southern part of the Moon's far side. It is nearly attached to the southeast rim of the larger crater Bose, and the outer rampart of that crater has produced a slight inward bulge along the northwest face of Bhabha. Other nearby craters of note include Stoney to the east, and Bellinsgauzen to the south.

Casatus (crater) impact crater

Casatus is a lunar impact crater that is located near the southern limb of the Moon. The north-northeast rim of the crater overlies a portion of the slightly larger crater Klaproth. Along the western rim, Casatus A intrudes somewhat into the interior, producing an inward-bowing rim. To the southeast of Casatus is Newton.

Demonax (crater) impact crater

Demonax is a lunar impact crater near the southern limb of the Moon. This location makes the crater difficult to observe due to foreshortening. The crater is also illuminated at a very low angle, when it is in the sunlit side. Demonax lies just to the north of the crater Scott, one of the south polar formations. To the north-northwest is Boguslawsky.

Chebyshev (crater) lunar 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.

Chappell (crater) lunar crater

Chappell is a lunar impact crater that is located on the far side of the Moon, in the northern hemisphere just to the north of the crater Debye. This feature is located in a heavily bombarded section of the surface, and much of the outer rim of the crater is overlain by many smaller craters. The northern rim in particular has been almost completely disintegrated, while small craters also overlie the rim to the northwest and southeast. What remains of the rim forms a rounded, somewhat irregular edge to the crater depression.

Chevallier (crater) impact crater

Chevallier is a lunar impact crater that is located in the northeastern part of the Moon's near side, about a crater diameter east-southeast of the prominent crater Atlas. To the south-southeast of Chevallier is the flooded crater Shuckburgh.

Drebbel (crater) impact crater

Drebbel is a small lunar impact crater named after Cornelius Drebbel that is located to the northeast of the large walled plain Schickard, in the southwestern part of the Moon. Further to the northeast is the Lacus Excellentiae and the small crater Clausius.

Faye (crater) lunar crater

Faye is a heavily eroded lunar impact crater in the rugged southern highlands of the Moon. It is named after French astronomer Hervé Faye. It is attached to the northeastern rim of the crater Delaunay, with Donati located just a few kilometers to the northeast. It forms part of a chain of craters of increasing size to the southwest that continues with La Caille and ends with the walled plain Purbach.

Dziewulski is a lunar impact crater on the far side of the Moon. It lies between the craters Edison to the north and Popov to the south. The outer rim of this crater has been considerably worn by impacts, particularly along the southwest quadrant where the satellite crater Dziewulski Q overlies the rim and the interior floor. The northern rim is also heavily disrupted, and several small crater lie along the southeast rim. The interior floor and surrounding terrain has been resurfaced.
