Français : Diagramme de la structure interne de Ganymède , un satellite de Jupiter et la plus grande lune du Système solaire. Ce noyau était plus chaud dans le passé. BEFORE the recent fly-bys of Ganymede by the Galileo spacecraft, viable models of the internal structure of Jupiter's largest moon ranged from a … Ganymede texture from File:Noaa ganymede.jpg.

The detection of The permanent magnetic moment carves a part of space around Ganymede, creating a tiny The interaction between the Ganymedian magnetosphere and Jovian In addition to the intrinsic magnetic moment, Ganymede has an induced dipole magnetic field.Given that Ganymede is completely differentiated and has a metallic core,Despite the presence of an iron core, Ganymede's magnetosphere remains enigmatic, particularly given that similar bodies lack the feature.The radiation level at the surface of Ganymede is considerably lower than at Europa, being 50-80 mSv (5-8 rem) per day, an amount that would cause severe illness or death in human beings exposed for two months.After formation, Ganymede's core largely retained the heat accumulated during accretion and differentiation, only slowly releasing it to the ice mantle.Several probes flying by or orbiting Jupiter have explored Ganymede more closely, including four flybys in the 1970s, and multiple passes in the 1990s to 2000s. Ganymede from Marc-Antoine Barrois offers a dreamlike ride on the shores of Lake Maggiore. Ganymede from Marc-Antoine Barrois offers a dreamlike ride on the shores of Lake Maggiore. Structure interne de Ganymède G anymède possède un noyau en fer pouvant contenir du soufre. 1998, assuming a Quinn Passey & E.M. Shoemaker (1982) "Craters on Ganymede and Callisto", in David Morrison, ed., E.M. Shoemaker et al. The study showed that these furrows form giant, concentric rings over the entire satellite. It is hoped that this exploration will confirm the results of this study and further advance our understanding of the formation and evolution of Jupiter’s satellites.The research team consisted of Kobe University Graduate School of Science’s Assistant Professor HIRATA Naoyuki and Professor OHTSUKI Keiji (both of the Department of Planetology), and Associate Professor SUETSUGU Ryo of National Institute of Technology, Oshima College. In addition, the Galileo spacecraft orbited Jupiter from 1995 to 2003, obtaining a large amount of Ganymede image data. It is believed that such an impact occurred around 40 million years ago.The discovery that the aftermath of a large-scale impact remains on Ganymede’s surface is greatly significant in terms of the satellite’s formation process and evolution.
Ganymede is the largest satellite in the solar system and is bigger than both Pluto and Mercury. [4] [62] [63] The precise thicknesses of the different layers in the interior of Ganymede depend on the assumed composition of silicates (fraction of olivine and pyroxene ) and amount of sulfur in the core. Consequently, there are various ongoing and planned spacecraft missions to explore the satellite system, including NASA’s JUNO mission that is ongoing, the Europa Clipper scheduled to perform a detailed investigation of Jupiter’s moon Europa in around 2030, and the aforementioned JUICE mission.The study was conducted with the aims of clarifying one aspect of the formation and evolution of Jupiter’s satellites and of contributing towards these spacecraft missions.
