Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. 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 are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ...

Eponym
An eponym is a noun after which or for which someone or something is, or is believed to be, named. Adjectives derived from the word ''eponym'' include ''eponymous'' and ''eponymic''. Eponyms are commonly used for time periods, places, innovations, biological nomenclature, astronomical objects, works of art and media, and tribal names. Various orthographic conventions are used for eponyms. Usage of the word The term ''eponym'' functions in multiple related ways, all based on an explicit relationship between two named things. ''Eponym'' may refer to a person or, less commonly, a place or thing for which someone or something is, or is believed to be, named. ''Eponym'' may also refer to someone or something named after, or believed to be named after, a person or, less commonly, a place or thing. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era, but the Elizabethan ...

Mondamin (crater)
Ceres is a dwarf planet in the asteroid belt that lies between the orbits of Mars and Jupiter. The IAU has adopted two themes for naming surface features on Ceres: agricultural deities for craters and agricultural festivals for everything else. As of 2020, the IAU has approved names for 151 geological features on Ceres: craters, montes, catenae, rupēs, plana, tholi, planitiae, fossae and sulci. In July 2018, NASA released a comparison of physical features found on Ceres with similar ones present on Earth. ''Piazzi'', named after Giuseppe Piazzi, the discoverer of Ceres, is a dark region southwest of Dantu crater in ground-based images that was named before ''Dawn'' arrived at Ceres.

Kerwan (crater)
Kerwan () is the largest confirmed impact basin and one of the largest geological features on the dwarf planet Ceres. It was discovered on February 19, 2015 from ''Dawn'' images as it approached Ceres. The crater is distinctly shallow for its size, and lacks a central peak. A central peak might have been destroyed by a 15-kilometer-wide crater at the center of Kerwan. The crater is likely to be young relative to the rest of Ceres's surface, as Kerwan has largely obliterated the cratering in the southern part of Vendimia Planitia.Marchi, S et al. “The missing large impact craters on Ceres.” Nature communications vol. 7 12257. 26 Jul. 2016, doi:10.1038/ncomms12257 Kerwan is roughly antipodal to Ahuna Mons, the largest, or at least youngest, mountain on Ceres. Seismic energy from the Kerwan-forming impact may have focused on the opposite side of Ceres, fracturing the outer layers of the crust and facilitating the movement of high-viscosity cryomagma (consisting of muddy water ...

Haulani (crater)
Haulani is an impact crater located on the dwarf planet Ceres that contains "Spot 1", one of the bright spots observed by the ''Dawn'' spacecraft. The crater was named after Haulani, the Hawaiian goddess of plants. In July 2018, NASA released a comparison of physical features, including Haulani crater, found on Ceres with similar ones present on Earth. Geology Haulani is located near the western edge of a plateau, with two small dome-shaped mountains—Dalien Tholus and an unnamed mountain—bordering the crater to the west. Haulani is surrounded by an extensive bright ejecta blanket that extends preferentially westward, with crater rays extending up to from Haulani's center. Structurally, Haulani's floor is dominated by a smooth plain, with the floor interrupted by cracks and pit chains to the northwest. An east-west oriented mountainous ridge roughly long and up to high occupies Haulani's center. As with many craters on Ceres, Haulani has been extensively modified by ...

Fejokoo (crater)
Fejokoo is a hexagonal impact crater on the dwarf planet Ceres. Like all craters on Ceres, it is named after an agricultural deity; the crater is named for the Igbo deity who provided yams. The name was officially approved by the International Astronomical Union (IAU) on 3 July 2015, shortly after ''Dawn'' had entered Ceres orbit. Fejokoo is the namesake for the Fejokoo Quadrangle. In contrast to typical impact craters, which are circular or elliptical in shape, Fejokoo resembles an equilateral hexagon—it is the largest polygonal crater on Ceres. As with most large craters on Ceres, Fejokoo's floor is generally flat and bounded by a very steep rim, with slopes exceeding 45° in some sections. The floor is roughly deep; the floor is interrupted at the center by a central peak roughly high. The hexagonal shape of Fejokoo likely comes from mass wasting processes such as landslides that have eroded the crater rim. The eastern and western rims are particularly affected, cont ...

Ezinu (crater)
Ezinu is a large impact crater on the dwarf planet Ceres, located on the edge of Hanami Planum. It was officially named on 3 July 2015 by the International Astronomical Union (IAU) after a Sumerian goddess of grain. It is the namesake of the Ezinu quadrangle, which covers a portion of Ceres's mid-latitude western hemisphere. Physical features Ezinu is large, at roughly in diameter. Its depth is when measured from its average crater rim elevation to the deepest point on its floor. It is significantly shallower than expected; a typical cerean crater of its size would be deep. Ezinu's shallow depth is influenced by the fact that its site of impact was on the northwest flank of Hanami Planum, a large highland area. As a result, its southeast crater floor is elevated—when measured from its highest rim section, Ezinu's depth is . Its floor hosts a system of fractures or troughs concentrated near the center. The largest trough is curved; it is roughly long, wide, and up to ...

Dantu (crater)
Dantu is a large crater on Ceres, located within the Vendimia Planitia. It is rimmed by a number of minor faculae, which together form Bright Spot 2. The crater is named after ''Dantu'', the timekeeper and first god of planting (millet) of the Gã people of Accra, Ghana.Marion Kilson (2013) ''Dancing with the Gods: Essays in Ga Ritual'' Dantu is thought to have formed Ma (million years) ago, based on the amount of crater impacts present within its ejecta blankets. The walls of Dantu are quite heavily eroded, with most of the north-eastern wall having collapsed completely. Due to Dantu's relatively young age, its crater floor is smooth, with few additional craters present within it. The crater floor also features a system of fractures, mostly located in the southern part of the crater. The center of Dantu is contains a peak, with a ring complex around it. The majority of Dantu's pit crater A pit crater (also called a subsidence crater or collapse crater) is a depression ...

Coniraya (crater)
Coniraya is a large, shallow impact crater on the dwarf planet Ceres. It is the namesake for the Coniraya Quadrangle. Naming The crater is named after the Incan lunar and fertility deity, Coniraya Viracocha (Kon Iraya Wiraqocha), who came to earth at Huarochirí (Waruchiri), and created villages, terraced fields and irrigation canals. The name was officially approved by the International Astronomical Union The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and developmen ... (IAU) on 3 July 2015. Geology Coniraya is an unusually shallow crater; despite having a diameter of roughly , it is only deep. This is in contrast to the neighboring crater Vinotonus, which is similar in size and age yet ten times deeper. The shallow depth of Coniraya may have been caused by viscous relaxation, though onl ...
