Gula (crater)
Gula is a crater Crater may refer to: Landforms *Impact crater, a depression caused by two celestial bodies impacting each other, such as a meteorite hitting a planet *Explosion crater, a hole formed in the ground produced by an explosion near or below the surfac ... on Ganymede. It is a fresh crater with a distinctive central peak. It is about 40 km (25 miles) in diameter. A characteristic feature of both Gula and its southern neighbor Achelous, almost identical in size, is the "pedestal" − an outward-facing, relatively gently sloped scarp that terminates the continuous ejecta blanket. Similar features may be seen in ejecta blankets of Martian craters, suggesting impacts into a volatile (ice)-rich target material. Furthermore, both craters appear crisp and feature terraces. Gula has a prominent central peak; Achelous instead may show the remnant of a collapsed central peak or a central pit that is not fully formed. On lower-resolution images taken under higher sun il ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gula (goddess)
Gula ( Sumerian: "the great") was a Mesopotamian goddess of medicine, portrayed as a divine physician and midwife. Over the course of the second and first millennia BCE, she became one of the main deities of the Mesopotamian pantheon, and eventually started to be viewed as the second highest ranked goddess after Ishtar. She was associated with dogs, and could be depicted alongside these animals, for example on ''kudurru'' (inscribed boundary stones), and receive figurines representing them as votive offerings. While Gula was initially regarded as unmarried, in the Kassite period she came to be associated with Ninurta. In Babylon his role could also be fulfilled by Mandanu, while the god list ''An = Anum'' links Gula with Pabilsag and Abu. The circle of deities closely associated with her also included Damu and Gunura, who eventually started to be regarded as her children, as well as her sukkal (divine vizier) Urmašum, who might have been imagined as a dog-like being.

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 ...

Ganymede (moon)
Ganymede, a satellite of Jupiter (Jupiter III), is the largest and most massive of the Solar System's moons. The ninth-largest object (including the Sun) of the Solar System, it is the largest without a substantial atmosphere (albeit not the most massive one, which is Mercury). It has a diameter of , making it 26 percent larger than the planet Mercury by volume, although it is only 45 percent as massive. Possessing a metallic core, it has the lowest moment of inertia factor of any solid body in the Solar System and is the only moon known to have a magnetic field. Outward from Jupiter, it is the seventh satellite and the third of the Galilean moons, the first group of objects discovered orbiting another planet. Ganymede orbits Jupiter in roughly seven days and is in a 1:2:4 orbital resonance with the moons Europa and Io, respectively. Ganymede is composed of approximately equal amounts of silicate rock and water. It is a fully differentiated body with an iron-rich, liq ...
