Gerin is 445 km (313 mile) wide impact crater on Saturn's moon Iapetus, located on Saragossa Terra. It is partially obscured by the larger crater, Engelier, whose formation has destroyed about half of Gerin. Gerin is located at 45°36′S233°00′W / 45.6°S 233°W Coordinates: 45°36′S233°00′W / 45.6°S 233°W [1]
Crater Gerin is named after one of the Twelve Peers in the French epic Song of Roland; [2] this name was approved by the International Astronomical Union in 2008.
An impact crater is a 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. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth.
In Greek mythology, Iapetus, also Japetus, is a Titan, the son of Uranus and Gaia and father of Atlas, Prometheus, Epimetheus, and Menoetius. He was also called the father of Buphagus and Anchiale in other sources.
Iapetus is the third-largest natural satellite of Saturn and the eleventh-largest in the Solar System. Discoveries by the Cassini mission in 2007 revealed several unusual features, such as a massive equatorial ridge running three-quarters of the way around the moon and a distinctive color pattern.

Murfreesboro is a city in, and the county seat of, Pike County, Arkansas, United States. Its population was 1,641 at the 2010 census. The city is known for the Crater of Diamonds State Park located south of the city.

Glen Lyn is a town in Giles County, Virginia, United States, at the confluence of the East and New rivers. The population was 115 at the 2010 census, down from 151 at the 2000 census. It is part of the Blacksburg–Christiansburg Metropolitan Statistical Area.
Hyperion, also known as Saturn VII, is a moon of Saturn discovered by William Cranch Bond, his son George Phillips Bond and William Lassell in 1848. It is distinguished by its irregular shape, its chaotic rotation, and its unexplained sponge-like appearance. It was the first non-round moon to be discovered.
Phoebe is an irregular satellite of Saturn with a mean diameter of 213 km (132 mi). It was discovered by William Henry Pickering on March 18, 1899 from photographic plates that had been taken starting on 16 August 1898 at the Boyden Station of the Carmen Alto Observatory near Arequipa, Peru, by DeLisle Stewart. It was the first satellite to be discovered photographically.
The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to enormous Titan, which is larger than the planet Mercury. Saturn has 83 moons with confirmed orbits that are not embedded in its rings—of which only 13 have diameters greater than 50 kilometers—as well as dense rings that contain millions of embedded moonlets and innumerable smaller ring particles. Seven Saturnian moons are large enough to have collapsed into a relaxed, ellipsoidal shape, though only one or two of those, Titan and possibly Rhea, are currently in hydrostatic equilibrium. Particularly notable among Saturn's moons are Titan, the second-largest moon in the Solar System, with a nitrogen-rich Earth-like atmosphere and a landscape featuring dry river networks and hydrocarbon lakes, Enceladus, which emits jets of gas and dust from its south-polar region, and Iapetus, with its contrasting black and white hemispheres.
Wunda is a large crater on the surface of Uranus' moon Umbriel. It is 131 km in diameter and is located near the equator of Umbriel. The crater is named after Wunda, a dark spirit of Australian aboriginal mythology.
Acraman crater is a deeply eroded impact crater in the Gawler Ranges of South Australia. Its location is marked by Lake Acraman, a circular ephemeral playa lake about 20 kilometres (12 mi) in diameter. The discovery of the crater and independent discovery of its ejecta were first reported in the journal Science in 1986. The evidence for impact includes the presence of shatter cones and shocked quartz in shattered bedrock on islands within Lake Acraman.
Jezero is a crater on Mars in the Syrtis Major quadrangle, about 45.0 km (28.0 mi) in diameter. Thought to have once been flooded with water, the crater contains a fan-delta deposit rich in clays. The lake in the crater was present when valley networks were forming on Mars. Besides having a delta, the crater shows point bars and inverted channels. From a study of the delta and channels, it was concluded that the lake inside the crater probably formed during a period in which there was continual surface runoff.
Turgis is the largest known crater on Saturn's moon Iapetus. It is 580 km in diameter, 40% of the moon's diameter and one of the larger craters in the Solar System. It is named after a Saracen baron, Turgis of Turtelose (Tortosa).
Mons is a mountain on a celestial body. The term is used in planetary nomenclature: it is a part of the international names of such features. It is capitalized and usually stands after the proper given name, but stands before it in the case of lunar mountains.
Saragossa Terra is the name given to the southern part of the highly reflective half of Saturn's moon Iapetus. It is bordered on the north by Roncevaux Terra, and on both the east and west sides by Cassini Regio.
Engelier is a 310-mile (500-kilometers) large crater on Saturn's moon Iapetus in Saragossa Terra. It partially obscures the slightly smaller crater Gerin.
Abisme /æˈbiːm/ is located in Cassini Regio at 37.9°N 267.1°E. Craters Climborin, Clarin, Dapamort, Johun and Valdebron can be found inside Abisme. It was imaged for the first time by the Cassini spacecraft in 2004.
