The dipole magnetic field created by this permanent moment has a strength of 719 ± 2 nT at Ganymede's equator, [23] which should be compared with the Jovian magnetic field at the distance of Ganymede—about 120 nT. [95] The equatorial field of Ganymede is directed against the Jovian field, meaning reconnection is possible. The intrinsic field ...

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
Mr King said: “This has allowed us to carry out detailed mapping of Europa and Ganymede, observing features on their surfaces smaller than 150km across – all at distances over 600 million ...
Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.
One way to decrease loss from sputtering is for the moon to have a strong magnetic field of its own that can deflect stellar wind and radiation belts. NASA's Galileo ' s measurements suggest that large moons can have magnetic fields; it found Ganymede has its own magnetosphere, even though its mass is only 2.5% of Earth's. [18]
The image depicts magnetic field of the Jovian satellite Ganymede embedded into the magnetosphere of Jupiter. The image is based on the reported Galileo measurements. [1] [2] The green color denotes closed field lines. The model used for this work is a superposition of the background Jovian field (120 nT) and the intrinsic field (720 nT at the ...
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.
