Eponym | Christoph Scheiner |
Scheiner is a lunar impact crater that lies to the west of the enormous walled plain Clavius. To the southeast near the rim of Clavius is the crater Blancanus. The rim of Scheiner is worn, eroded, and marked with multiple impacts. It is most heavily worn in the northern part, where a cluster of craterlets covers the entrance to a low valley leading to the north. The floor of the crater has several craterlets, including Scheiner A that lies near the midpoint. There is also a low ridge crossing part of the eastern floor.
Lunar craters are impact craters on Earth's Moon. The Moon's surface has many craters, almost all of which were formed by impacts.
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.
Clavius is one of the largest crater formations on the Moon, and it is the second largest crater on the visible near side. It is located in the rugged southern highlands of the Moon, to the south of the prominent ray crater Tycho. The crater is named for the Jesuit priest Christopher Clavius, a 16th-century German mathematician and astronomer.
By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Scheiner.

Anaximenes is a low-rimmed lunar impact crater near the north-northwest limb of the Moon. It lies to the west of the crater Philolaus, and northeast of Carpenter. To the northwest is Poncelet, close to the visible edge of the Moon.
Blancanus is a lunar impact crater located in the rugged southern region of the Moon, to the southwest of the walled plain Clavius. To the northwest lies the comparably sized crater Scheiner, and south-southwest of Blancanus is the worn Klaproth.
Arrhenius is a lunar impact crater that is located just on the far side of the Moon, near the southwest limb. In this location the vicinity of the crater can be viewed during favorable librations, although it is viewed from on edge. To the south-southeast is the worn crater Blanchard, and De Roy lies further to the west.
Baco is a lunar impact crater that lies in the rugged southern highlands on the near side of the Moon. The rim and inner wall has been eroded and worn by countless minor impacts since the original formation of the crater. As a result, any terraces have been worn smooth and the rim is overlaid by several tiny craterlets. The interior floor is nearly flat, with no characteristic central peak at the midpoint and no small craters of significance.
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.
Boltzmann is an old lunar impact crater that is located along the southern limb of the Moon, in the vicinity of the south pole. At this location the crater is viewed from the side from Earth, and so not much detail can be seen. It is located to the north of the walled plain Drygalski, and to the west of the crater Le Gentil.
Rost is a lunar impact crater that is located in the southwestern part of the Moon, to the southeast of the elongated formation Schiller. To the southeast of Rost is the larger crater Scheiner. West-southwest of this formation is the smaller Weigel.
Porter is a lunar impact crater that is located in the southern part of the Moon, and lies across the northeastern rim of the huge walled plain Clavius. Although generally circular, the form of this crater has been modified by the geometry of the surface on which it was formed. The outer rim is generally lower to the southwest, where it lies on the floor of Clavius. Likewise the interior floor is flatter near this face. In contrast the northeastern floor is rougher and more uneven in the northeastern half.
Beijerinck is a lunar impact crater on the far side of the Moon. It lies to the south of the larger crater Chaplygin, and to the northeast of the huge walled plain Gagarin.
Carver is a lunar impact crater that is located on the far side of the Moon, due east of the walled plain Van der Waals. To the northeast is the crater Rosseland, and to the south-southeast lies Kozyrev.
Cannizzaro is a lunar impact crater that is located on the Moon's far side as seen from the Earth, just beyond the northwestern limb. It lies in a region of the surface that is sometimes brought into view due to the effects of libration, but not much detail can be seen since this feature is viewed from the side. The crater lies across the southwestern rim of the much larger-walled plain Poczobutt.
Dove is a small lunar impact crater that is located in the rugged lunar highlands in the southeastern part of the Moon. It lies to the north of the prominent crater Pitiscus.
Hagecius is a lunar impact crater in the southeastern part of the Moon's near side. It was named after 16th century Czech naturalist Tadeáš Hájek. This crater forms a triangular formation with the craters Rosenberger to the north-northwest and Nearch to the west-northwest. Like both of these craters, Hagecius has undergone erosion from subsequent impacts, and its outer rim is worn and irregular. The southeastern rim in particular is overlaid by three smaller craters designated Hagecius C, B, and G.
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.
Eijkman is a lunar impact crater that is located on the far side of the Moon's southern hemisphere. It lies about a half crater diameter to the southeast of the larger crater Lemaître. To the south-southwest is the crater Crommelin, and to the northeast is Fizeau.
Evershed is a lunar impact crater on the far side of the Moon, named after the English solar astronomer John Evershed. It is located to the northeast of the larger crater Cockcroft, and to the north of the smaller Van den Bergh.
Fowler is a large lunar impact crater that lies in the northern hemisphere on the Moon's far side. It lies to the south-southwest of the crater Esnault-Pelterie, and north of Gadomski. Overlying the eastern rim and intruding into the interior is Von Zeipel.
Love is an impact crater on the far side of the Moon. It was named after British mathematician and geophysicist Augustus Edward Hough Love. It is located just to the north of the crater Perepelkin. Prager nearly touches the northeastern rim. To the northwest is Bečvář.
Schuster is a lunar impact crater that lies along the eastern rim of the much larger walled plain Mendeleev, on the far side of the Moon. To the east of Schuster is the crater Henderson, and to the southeast lies the large Chaplygin.
Ewen Adair Whitaker was a British-born astronomer who specialized in lunar studies. During World War II he was engaged in quality control for the lead sheathing of hollow cables strung under the English Channel as part of the "Pipe Line Under The Ocean" Project (PLUTO) to supply gasoline to Allied military vehicles in France. After the war, he obtained a position at the Royal Greenwich Observatory working on the UV spectra of stars, but became interested in lunar studies. As a sideline, Whitaker drew and published the first accurate chart of the South Polar area of the Moon in 1954, and served as director of the Lunar Section of the British Astronomical Association.
