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'' () is an 11th-century based on the deeds of the Frankish military leader Roland at the Battle of Roncevaux Pass in AD 778, during the reign of the Emperor Charlemagne.

Planetary Nomenclature
Planetary nomenclature, like terrestrial nomenclature, is a system of uniquely identifying features on the surface of a planet or natural satellite so that the features can be easily located, described, and discussed. Since the invention of the telescope, astronomers have given names to the surface features they have discerned, especially on the Moon and Mars. To found an authority on planetary nomenclature, the International Astronomical Union (IAU) was organized in 1919 to designate and standardize names for features on Solar System bodies. IAU approval procedure When images are first obtained of the surface of a planet or satellite, a theme for naming features is chosen and a few important features are named, usually by members of the appropriate IAU task group (a commonly accepted planet-naming group). Later, as higher resolution images and maps become available, additional features are named at the request of investigators mapping or describing specific surfaces, fe ...

Iapetus (moon)
Iapetus () is the outermost of Moons of Saturn, Saturn's large moons. With an estimated diameter of , it is the third-largest moon of Saturn and the List of natural satellites, eleventh-largest in the Solar System. Named after the Titans, 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 on Iapetus, 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. This is the first moon that Cassini discovered; the second moon of Saturn to be discovered after Christiaan Huygens spotted Titan (moon), Titan 16 years prior in 1655; and the sixth ...
