A montage of Jupiter and its four largest moons (distance and sizes not to scale) There are 95 moons of Jupiter with confirmed orbits as of 5 February 2024. [1] [note 1] This number does not include a number of meter-sized moonlets thought to be shed from the inner moons, nor hundreds of possible kilometer-sized outer irregular moons that were only briefly captured by telescopes. [4]
Some models predict that there may have been several generations of Galilean satellites in Jupiter's early history. Each generation of moons to have formed would have spiraled into Jupiter and been destroyed, due to tidal interactions with Jupiter's proto-satellite disk, with new moons forming from the remaining debris. By the time the present ...
As the below graph demonstrates, the maximum absolute magnitude (total inherent brightness, abbreviated H) of moons we have detected around planets occurs at H = 18 for Jupiter, H = 17 for Saturn, H = 14 for Uranus, and H = 12 for Neptune. Smaller moons may (and most likely do) exist around each of these planets, but are currently undetectable ...
The Pluto-bound New Horizons spacecraft passed by Jupiter in 2007 and made improved measurements of its and its satellites' parameters. The Galileo spacecraft was the first to have entered orbit around Jupiter, arriving in 1995 and studying the planet until 2003.
Ganymede is the only Galilean moon of Jupiter named after a male figure—like Io, Europa, and Callisto, he was a lover of Zeus. In English, the Galilean satellites Io, Europa and Callisto have the Latin spellings of their names, but the Latin form of Ganymede is Ganymēdēs, which would be pronounced / ˌ ɡ æ n ɪ ˈ m iː d iː z /.

Jupiter LVI, provisionally known as S/2011 J 2, is a natural satellite of Jupiter.It was discovered by Scott Sheppard in 2011. [2] [3] Images of the newly discovered moon were captured using the Magellan-Baade telescope at the Las Campanas Observatory in Chile.
S/2003 J 12 is a natural satellite of Jupiter, and is one of the smallest known natural satellites in the Solar System.It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003.
Cyllene / s ə ˈ l iː n iː /, also known as Jupiter XLVIII, is a natural satellite of Jupiter.It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003, receiving the temporary designation S/2003 J 13.
