Kidinnu is an impact crater on the Moon's far side. It lies to the south of the crater H. G. Wells and to the southeast of Cantor.

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.

H. G. Wells (crater) lunar crater

H. G. Wells is a lunar impact crater that is located on the far side of the Moon, behind the northeastern limb. It lies to the south of the crater Millikan, and to the northeast of Cantor. Just to the southeast is the smaller Tesla.

This is a somewhat unevenly formed crater with an outer rim that forms a rounded polygon. The inner wall varies in width, with the narrowest stretch along the outward-bulging northeast. There are no craters of note along the rim or within the interior. The interior floor is uneven, with a central ridge that runs to the southern edge.

In elementary geometry, a polygon is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit. The solid plane region, the bounding circuit, or the two together, may be called a polygon.

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 Kidinnu.

Cantor (crater) lunar crater

Cantor is a lunar impact crater that is located on the northern hemisphere on the far side of the Moon. The outer rim of the crater has a distinctly hexagonal shape, and is slightly longer in the north–south direction. The interior walls are multiply terraced, although less so along the western rim. There is a low central peak at the midpoint of the floor.

Porter (lunar crater) lunar crater

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.

Gaudibert (crater) impact crater

Gaudibert is a lunar impact crater that lies along the northeast edge of Mare Nectaris in the eastern part of the Moon's near side. Just to the east is the Montes Pyrenaeus mountain chain, and to the northeast beyond the mountains is the crater Gutenberg. Northwest of Gaudibert is the crater pair Isidorus and Capella.

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.

Delaunay (crater) lunar crater

Delaunay is a lunar impact crater. It was named after French astronomer Charles-Eugène Delaunay. The craters La Caille to the southwest and Faye to the northeast border on the outer rim of Delaunay. Further to the northwest is the prominent Arzachel.

Charlier (lunar crater) lunar crater

Charlier is a lunar impact crater that is located on the far side of the Moon. To the south-southeast is the larger crater Kovalevskaya, and northeast of Charlier is Perrine.

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.

Cockcroft (crater) lunar crater

Cockcroft is a lunar impact crater that is situated on the far side of the Moon from the Earth, so that it has only be observed and photographed from orbit. It lies to the northeast of the larger crater Fitzgerald, and southeast of Evershed.

Chappe (crater) lunar crater

Chappe is a lunar impact crater that lies along the southwestern limb of the Moon. It is nearly attached to the northern limb of the walled plain Hausen, and an equal distance from the crater Pilâtre. To the north-northwest is Blanchard.

Dante (crater) lunar crater

Dante is a lunar impact crater that is located on the far side of the Moon. It lies in the northern hemisphere exactly opposite the prime meridian facing the Earth. The nearest craters of note are Larmor to the north and Morse to the southeast. To the southwest is the oddly shaped Buys-Ballot.

Eötvös (crater) lunar crater

Eötvös is the remains of a lunar impact crater on the far side of the Moon. It lies to the north-northwest of the walled plain Roche, and east-southeast of the equally ruined Bolyai.

Erro (crater) impact crater

Erro is a lunar impact crater that lies beyond the eastern limb of the Moon, on the far side as seen from the Earth. It lies along the eastern fringes of the uneven plain that joins Mare Marginis to the northwest with Mare Smythii to the west-southwest. This part of the surface is sometimes brought into sight of observers on the Earth due to libration. However even at such times not much detail can be seen, as the surface is viewed from the edge.

Fesenkov is a lunar impact crater on the far side of the Moon. It is located to the east-southeast of the prominent crater Tsiolkovskiy, and less than a crater diameter to the north of Stark.

Florensky (crater) lunar crater

Florensky is a lunar impact crater that is attached to the northeastern rim of the larger crater Vernadskiy. It is located on the far side of the Moon and cannot be directly seen from the Earth. The rim of this crater has been heavily eroded and it forms an irregular ring about the uneven interior. This crater was previously identified as Vernadskiy B before being assigned a name by the IAU in 1985.

Hogg (crater) lunar crater

Hogg is a lunar impact crater on the Moon's far side. It lies less than a crater diameter to the south-southwest of the somewhat larger Kidinnu. This is an old, worn feature with an outer rim that has been eroded to the point where it just forms a rounded crest about the interior. Small craterlets lie along the southern and western rim. The interior has some slight clefts in the surface and a low, crater-like depression in the southern half.

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.
