On 8 September 2014, NASA reported finding evidence of plate tectonics on Europa, a satellite of Jupiter—the first sign of subduction activity on another world other than Earth. [2] Titan , the largest moon of Saturn , was reported to show tectonic activity in images taken by the Huygens probe , which landed on Titan on January 14, 2005.
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.
This formula is a simplified version of that in section 2.2 of Stansberry et al., 2007, [39] where emissivity and beaming parameter were assumed to equal unity, and was replaced with 4, accounting for the difference between circle and sphere. All parameters mentioned above were taken from the same paper.
There are two Io-Europa conjunctions (green) and three Io-Ganymede conjunctions (grey) for each Europa-Ganymede conjunction (magenta). This diagram is not to scale. In celestial mechanics , orbital resonance occurs when orbiting bodies exert regular, periodic gravitational influence on each other, usually because their orbital periods are ...

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
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 ...
In solid-state physics, the free electron model is a quantum mechanical model for the behaviour of charge carriers in a metallic solid. It was developed in 1927, [1] principally by Arnold Sommerfeld, who combined the classical Drude model with quantum mechanical Fermi–Dirac statistics and hence it is also known as the Drude–Sommerfeld model.
