All together, Jupiter's moons form a satellite system called the Jovian system. The most massive of the moons are the four Galilean moons: Io, Europa, Ganymede, and Callisto, which were independently discovered in 1610 by Galileo Galilei and Simon Marius and were the first objects found to orbit a body that was neither Earth nor the Sun.

2025年2月11日 · Jupiter has 95 recognized moons as of 2023. The largest moons of Jupiter are the Galilean moons: Io, Europa, Ganymede, and Callisto. Ganymede is the largest moon in the solar system, surpassing Mercury in size with a diameter of 3,273 miles (5,262 kilometers).

Jupiter has four large moons which were discovered by Galileo in 1610 using a 20-power telescope. These moons are known as the Galilean moons and they are called Io, Europa, Ganymede and Callisto. Jupiter also has dozens of other smaller moons that are thought to have originated from passing asteroids. So how many moons does Jupiter have?

Jupiter has 80 total numbers of moons, of which 23 have not been officially named yet. So there are 57 confirmed Jupiter moons with their official names.
