Lunar craters craters on Earths moon

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

The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite. It is the fifth-largest natural 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.

This is a relatively worn formation with the satellite crater Deluc H intruding into the northeast rim. A triangular bulge of material covers the floor from the rim of this intruding crater to near the midpoint of the interior. The small craterlet Deluc T is attached to the southern outer rim of Deluc, and joins it to the small Deluc D to the south. [2]

The remaining rim of Deluc is not quite circular, having a slight outward bulge to the northwest. The interior is worn and smoothed from a history of tiny impacts, although the edge is still well-defined. There is a tiny craterlet in the northeast part of the interior, but most of the remainder of the floor is level and marked only by tiny impacts. [2]

The crater is named for Jean-André Deluc, an 18th-century Swiss geologist and physicist. [1]

Jean-André Deluc Swiss geologist and meteorologist

Jean-André Deluc or de Luc was a Swiss geologist, natural philosopher and meteorologist. He also devised measuring instruments.

Switzerland federal republic in Western Europe

Switzerland, officially the Swiss Confederation, is a country situated in western, central and southern Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The sovereign state is a federal republic bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning a total area of 41,285 km2 (15,940 sq mi). While the Alps occupy the greater part of the territory, the Swiss population of approximately 8.5 million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva.

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 Deluc. [3]

Almanon (crater) impact crater

Almanon is a lunar impact crater that lies in the rugged highlands in the south-central region of the Moon. It was named after Abbasid Caliph and astronomer Al-Ma'mun. It is located to the south-southeast of Abulfeda, and to the north-northeast of the smaller crater Geber. The crater chain designated Catena Abulfeda forms a line between the south rim of Abulfeda and the north rim of Almanon, continuing for a length of about 210 kilometers to the Rupes Altai scarp.

Apianus (crater) impact crater

Apianus is a lunar impact crater that is located on the rugged south-central highlands of the Moon. It is named after 16th century German mathematician and astronomer Petrus Apianus. It is located to the northeast of the crater Aliacensis, and to the northwest of Poisson. The worn crater Krusenstern is attached to the west-northwestern rim.

Baillaud (crater) impact crater

Baillaud is a lunar impact crater that is located near the north limb of the Moon. The rim of the crater has been eroded and worn by a long history of impacts, leaving a hilly ridge surrounding the interior. The crater Euctemon is intruding into the rim to the northeast, and the rim bulges outward to the northwest. At the south end of the crater is a gap connecting to the lava-flooded surface to the south.

Brianchon (crater) lunar 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.

Boltzmann (crater) lunar crater

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.

Mutus is a lunar impact crater that is located in the rugged southern part of the Moon. It lies to the north-northeast of the larger crater Manzinus, and some distance to the south of Hommel. It is 78 kilometers in diameter and 3.7 kilometers deep. It is from the Pre-Nectarian period, 4.55 to 3.92 billion years ago.

De La Rue (crater) impact crater

De La Rue is the remnant of a lunar impact crater, or possibly several merged craters, creating a formation sometimes called a walled plain. It lies in the northeastern part of the Moon on the near side, and so appears foreshortened due to its location. This formation lies to the north-northwest of the prominent crater Endymion, just beyond the eastern extreme of Mare Frigoris. The crater Strabo intrudes into the northern part of De La Rue's northern rim, and the smaller Thales is attached to the northwestern part of the wall.

Fabry (crater) impact crater

Fabry is a large lunar impact crater of the form termed a walled plain. It is located on the far side of the Moon, just beyond the northeastern limb. Parts of this area are sometimes brought into view by the effects of libration, but the terrain is seen from the edge and so not much in the way of detail can be observed.

Curtius (crater) impact crater

Curtius is a lunar impact crater that is located in the southern part of the Moon. From the Earth the crater appears foreshortened, making it more difficult to observe detail. Nevertheless, this is a large crater that can be readily found in even small telescopes. Curtius is located within one crater diameter of the still-larger Moretus to the southwest. To the northeast is the smaller Pentland. Curtius is 95 kilometers in diameter and 6.8 kilometers deep. It is from the Nectarian period, 3.92 to 3.85 billion years ago.

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.

Mercurius (crater) impact crater

Mercurius is a lunar impact crater that is located in the northeastern part of the Moon. It lies to the northeast of the smaller crater Carrington, and west-northwest of Zeno. Just to the south is the small lunar mare named Lacus Spei, and to the west is the larger Lacus Temporis.
