  2. Ganymede (moon) - Wikipedia

    en.wikipedia.org/wiki/Ganymede_(moon)

    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

  5. Planetary-mass moon - Wikipedia

    en.wikipedia.org/wiki/Planetary-mass_moon

    (Ice has less tensile strength than rock, and is deformed at lower pressures and temperatures than rock.) 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 ...

  6. Habitability of natural satellites - Wikipedia

    en.wikipedia.org/wiki/Habitability_of_natural...

    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]

  7. Orders of magnitude (magnetic moment) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude...

    The magnetic moment of an object is an intrinsic property and does not change with distance, and thus can be used to measure "how strong" a magnet is. For example, Earth possesses an enormous magnetic moment, however we are very distant from its center and experience only a tiny magnetic flux density (measured in tesla ) on its surface.

  9. Europa (moon) - Wikipedia

    en.wikipedia.org/wiki/Europa_(moon)

    The Galileo orbiter found that Europa has a weak magnetic moment, which is induced by the varying part of the Jovian magnetic field. The field strength at the magnetic equator (about 120 nT) created by this magnetic moment is about one-sixth the strength of Ganymede's field and six times the value of Callisto's. [87]
