Jupiter is expected to have about 100 irregular moons larger than 1 km (0.6 mi) in diameter, plus around 500 more smaller retrograde moons down to diameters of 0.8 km (0.5 mi). [5] Of the 87 known irregular moons of Jupiter, 38 of them have not yet been officially named.
Jupiter is the largest planet in the solar system and has, as of 2023, 95 known moons. The four largest moons of Jupiter—Io, Callisto, Ganymede, and Europa—were the first objects in the solar system discovered with a telescope. Galileo discovered them in 1610, and they are now called the Galilean.

Jupiter's rocky moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high. Io’s remarkable activity is the result of a tug-of-war between Jupiter's powerful gravity and smaller but precisely timed pulls from two neighboring moons that orbit ...
