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]
Jupiter's moons were classified into four groups of four, based on their similar orbital elements. [204] This picture has been complicated by the discovery of numerous small outer moons since 1999. Jupiter's moons are divided into several different groups, although there are two known moons which are not part of any group (Themisto and Valetudo ...
The moon does not form part of the orbital resonance that affects three inner Galilean satellites and thus does not experience appreciable tidal heating. [47] Callisto is composed of approximately equal amounts of rock and ices , which makes it the least dense of the Galilean moons.
Every human language has its own word for the Earth's Moon, and these words are the ones normally used in astronomical contexts.However, a number of fanciful or mythological names for the Moon have been used in the context of astronomy (an even larger number of lunar epithets have been used in non-astronomical contexts).
Jupiter has 95 moons with known orbits; 72 of them have received permanent designations, and 57 have been named. Its eight regular moons are grouped into the planet-sized Galilean moons and the far smaller Amalthea group. They were named after lovers of Zeus, the Greek equivalent of Jupiter.
Jupiter has surpassed Saturn with the record for the planet with the most moons in our solar system. The gas giant has a total of 92 confirmed moons, according to new observations by astronomers.
Two of the new moons orbit in the same direction as the planet rotates, which requires a name that ends in -a; the other three travel in the opposite direction and will be given names that end in ...
