  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 ...

  3. Galilean moons - Wikipedia

    en.wikipedia.org/wiki/Galilean_moons

    Ganymede is the largest natural satellite in the Solar System at 5262.4 kilometers in diameter, which makes it larger than the planet Mercury – although only at about half of its mass [42] since Ganymede is an icy world.

  4. 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]

  5. Planetary-mass moon - Wikipedia

    en.wikipedia.org/wiki/Planetary-mass_moon

    Planetary-mass moons larger than Pluto, the largest Solar dwarf planet. A planetary-mass moon is a planetary-mass object that is also a natural satellite. They are large and ellipsoidal (sometimes spherical) in shape. Moons may be in hydrostatic equilibrium due to tidal or radiogenic heating, in some cases forming a subsurface ocean.

  6. 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.

    Last year, NASA released an audio representation of magnetic field activity around Jupiter's moon Ganymede. More recently, we got to hear a terrifying depiction of what a black hole sounds like.

  8. Planetary habitability in the Solar System - Wikipedia

    en.wikipedia.org/wiki/Planetary_habitability_in...

    The core, the likely cause of Ganymede's magnetic field, would have a temperature near 1600 K. This particular environment is suspected to be likely to be habitable. [ 23 ] The moon is set to be the subject of investigation by the European Space Agency 's Jupiter Icy Moons Explorer , which was launched in 2023 and will reach the Jovian system ...
