Gerin (crater)
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 Nomenclature Crater Gerin is named after one of the Twelve Peers in the French epic Song of Roland; this name was approved by the International Astronomical Union in 2008.

Iapetus As Seen By The Cassini Probe - 20071008
In Greek mythology, Iapetus (; ; grc, Ἰαπετός, Iapetós), 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 was linked to Japheth (יֶפֶת) one of the sons of Noah and a progenitor of mankind in biblical accounts. The practice by early historians and biblical scholars of identifying various historical nations and ethnic groups as descendants of Japheth, together with the similarity of their names, led to a fusion of their identities, from the early modern period to the present. Mythology Iapetus ("the Piercer") is the one Titan mentioned by Homer in the ''Iliad'' as being in Tartarus with Cronus. He is a brother of Cronus, who ruled the world during the Golden Age but is now locked up in Tartarus along with Iapetus, where neither breeze nor light of the sun reaches them. Iapetus' wife is usually described as a daughter o ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity 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. 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. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Moons Of Saturn
The moons of Saturn are numerous and diverse, ranging from tiny moonlets only tens of meters across to enormous Titan (moon), Titan, which is larger than the planet Mercury (planet), Mercury. Saturn has 83 natural satellite, moons with confirmed orbits that are not embedded in its Rings of Saturn, 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 (moon), Rhea, are currently in hydrostatic equilibrium. Particularly notable among Saturn's moons are Titan, the second-List of natural satellites, largest moon in the Solar System (after Jupiter's Ganymede (moon), Ganymede), with a Atmosphere of Titan#Composition, nitrogen-rich Earth-like Atmosphere of Titan, atmosphere and a landscape featuring dry river networks and ...

Iapetus (moon)
Iapetus () is a moon of Saturn. It is the 24th of Saturn’s 83 known moons. With an estimated diameter of 1,469 km, it is the third-largest moon of Saturn and the eleventh-largest in the Solar System. Named after the Titan Iapetus, the moon was discovered in 1671 by Giovanni Domenico Cassini. A relatively low-density body made up mostly of ice, Iapetus is home to several distinctive and unusual features, such as a striking difference in coloration between its leading hemisphere, which is dark, and its trailing hemisphere, which is bright, as well as a massive equatorial ridge running three-quarters of the way around the moon. History Discovery Iapetus was discovered by Giovanni Domenico Cassini, an Italian-born French astronomer, in October 1671. He had discovered it on the western side of Saturn and tried viewing it on the eastern side some months later, but was unsuccessful. This was also the case the following year, when he was again able to observe it on the western ...

Saragossa Terra
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. The largest named crater in Saragossa Terra is the 504-km-diameter Engelier. It partially obscures the slightly smaller crater Gerin. Both craters are named for paladins mentioned in The Song of Roland ''The Song of Roland'' (french: La Chanson de Roland) is an 11th-century '' chanson de geste'' based on the Frankish military leader Roland at the Battle of Roncevaux Pass in 778 AD, during the reign of the Carolingian king Charlemagne.

Twelve Peers
The Paladins, also called the Twelve Peers, are twelve legendary knights, the foremost members of Charlemagne's court in the 8th century. They first appear in the medieval (12th century) ''chanson de geste'' cycle of the Matter of France, where they play a similar role to the Knights of the Round Table in Arthurian romance."Paladin"

The Song Of Roland
''The Song of Roland'' (french: La Chanson de Roland) is an 11th-century ''chanson de geste'' based on the Frankish military leader Roland at the Battle of Roncevaux Pass in 778 AD, during the reign of the Carolingian king Charlemagne. It is the oldest surviving major work of French literature. It exists in various manuscript versions, which testify to its enormous and enduring popularity in Medieval and Renaissance literature from the 12th to 16th centuries. The epic poem written in Vulgar Latin is the first and one of the most outstanding examples of the ''chanson de geste'', a literary form that flourished between the 11th and 16th centuries in Medieval Europe and celebrated legendary deeds. The date of composition is put in the period between 1040 AD and 1115 AD; an early version began around 1040 AD with additions and alterations made up until about 1115 AD. The final text contains about 4,000 lines of poetry. Manuscripts and dating Although set in the Carolingian era, ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ...
