Ganymede, or Jupiter III, is the largest and most massive natural satellite of Jupiter, and in the Solar System.Despite being the only moon in the Solar System with a substantial magnetic field, it is the largest Solar System object without a substantial atmosphere.
The largest, Ganymede, is the largest moon in the Solar System and surpasses the planet Mercury in size (though not mass). Callisto is only slightly smaller than Mercury in size; the smaller ones, Io and Europa, are about the size of the Moon. The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with
Zeus pursues Ganymede on one side, while the youth runs away on the other side, rolling along a hoop while holding aloft a crowing cock. The Ganymede myth was depicted in recognizable contemporary terms, illustrated with common behavior of homoerotic courtship rituals, as on a vase by the "Achilles Painter" where Ganymede also flees with a cock.
The images provide new insights into the chemical composition of two of Jupiter’s moons.
Galileo Regio is a large, dark surface feature on Jupiter's moon Ganymede. [1] It is a region of ancient dark material that has been broken apart by tectonism and is now surrounded by younger, brighter material (such as that of Uruk Sulcus) that has been upwelling from Ganymede's interior. It is thought to be some 4 billion years old and is ...
Many other natural satellites, such as Earth's Moon, Ganymede, Tethys, and Miranda, show evidence of past geological activity, resulting from energy sources such as the decay of their primordial radioisotopes, greater past orbital eccentricities (due in some cases to past orbital resonances), or the differentiation or freezing of their interiors.
Abundant evidence of strike-slip faulting on Ganymede exists in both bright and dark terrain types. [13] Such faulting may expose fresh, light ice within dark terrains. [13] The fields of mapped faults may give evidence of how stress patterns shifted through time to produce the terrain. [13]
The evidence is perhaps strongest for Ganymede, which has a magnetic field that indicates the fluid movement of electrically conducting material in its interior, though whether that fluid is a metallic core or a subsurface ocean is unknown. [15]
