Moons of Jupiter. 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 ...
From top to bottom: Io, Europa, Ganymede, Callisto. The Galilean moons ( / ˌɡælɪˈleɪ.ən / ), [1] or Galilean satellites, are the four largest moons of Jupiter: Io, Europa, Ganymede, and Callisto. They are the most readily visible Solar System objects after Saturn, the dimmest of the classical planets; though their closeness to bright ...
Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar System.
Callisto ( / kəˈlɪstoʊ / kə-LIST-oh ), or Jupiter IV, is the second-largest moon of Jupiter, after Ganymede. In the Solar System it is the third-largest moon after Ganymede and Saturn 's largest moon Titan, and as large as the smallest planet Mercury. Callisto is, with a diameter of 4,821 km, roughly a third larger than Earth's Moon and ...
Size. With a diameter of about 5,270 kilometres (3,270 mi) and a mass of 1.48 × 10 20 tonnes (1.48 × 10 23 kg; 3.26 × 10 23 lb), Ganymede is the largest and most massive moon in the Solar System. [ 44] It is slightly more massive than the second most massive moon, Saturn's satellite Titan, and is more than twice as massive as the Earth's ...

Io is slightly larger than Earth's Moon. It has a mean radius of 1,821.3 km (1,131.7 mi) (about 5% greater than the Moon's) and a mass of 8.9319 × 10 22 kg (about 21% greater than the Moon's). It is a slight ellipsoid in shape, with its longest axis directed toward Jupiter. Among the Galilean satellites, in both mass and volume, Io ranks ...
Adrastea. Hephaestus. Semele. Ananke. Danae. Current practice is that newly discovered moons of Jupiter must be named after lovers or descendants of the mythological Jupiter ( Zeus ). Blunck's scheme for the outer moons was retained, with the addition that names ending in 'o' could also be used for prograde moons.
