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 ...
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.
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]
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.
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.
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 ...
