Orbital diagram of the orbital inclination and orbital distances for Jupiter's rings and moon system at various scales. Notable moons, moon groups, and rings are individually labeled. Open the image for full resolution. The moons of Jupiter are listed below by orbital period.
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 has 95 moons that have been officially recognized by the International Astronomical Union. But the number doesn't capture the complexity of the Jovian system of moons, rings and asteroids. The giant planet has thousands of small objects in its orbit.

Aug 21, 2023 · All Moons of Jupiter. Most of Jupiter's swarms of smaller moons orbit much farther out than the Galilean satellites. Of these distant moons, the larger ones may be captured asteroids. The smaller ones are likely fragments from massive collisions.
Moons of Jupiter. 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.
Moons. With four large moons and many smaller moons, Jupiter forms a kind of miniature solar system. Jupiter has 80 moons. Fifty-seven moons have been given official names by the International Astronomical Union (IAU). Another 23 moons are awaiting names.
Callisto is Jupiter’s second largest moon and the third largest moon in our solar system. Its surface is the most heavily cratered of any object in our solar system. Images of Callisto captured by passing spacecraft show bright white spots standing out against darker regions.

Dec 26, 2023 · Jupiter’s Galilean moons are the closest large moons to Earth, and are therefore the most easily visible through a small telescope. Today, NASA’s Juno mission is in orbit around Jupiter, getting opportunities to observe some of its moons.
