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
The surface of Ganymede, a moon of Jupiter moon, is covered by furrows (right) that form concentric circles around one specific spot (left, red cross), which led researchers in the 1980s to ...
Io, Europa, Ganymede, Titan, and Triton are generally believed to be in hydrostatic equilibrium, but Earth's Moon is known not to be in hydrostatic equilibrium, and the situation for Callisto is unclear. Another dozen moons are ellipsoidal as well, indicating that they achieved equilibrium at some point in their histories.

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 in 2031.
