Aurorae on Ganymede—auroral belt shifting may indicate a subsurface saline ocean. The permanent magnetic moment carves a part of space around Ganymede, creating a tiny magnetosphere embedded inside that of Jupiter ; it is the only moon in the Solar System known to possess the feature. [ 95 ]
The latter can still freely strike Ganymede's poles, where the field lines are open. [79] Some of the energetic particles are trapped near the equator of Ganymede, creating mini-radiation belts. [80] Energetic electrons entering its thin atmosphere are responsible for the observed Ganymedian polar aurorae. [79]
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
The solar system's largest moon, Ganymede, which orbits the largest planet, Jupiter, was hit by an asteroid four billion years ago that shifted the gas giant's satellite on its axis, new research ...
Geologic Map of Ganymede (February 11, 2014). This is a list of named geological features, except craters, on Ganymede , a moon of Jupiter . The list is complete as of August 2022.
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 ...
Ganymede is the largest moon in the Solar System, and has a hard surface with many craters. Most of them are named after figures from Egyptian, Mesopotamian, and other ancient Middle Eastern myths.
