As of 2024, Jupiter had 95 confirmed moons. That count included the four large Galilean moons, several smaller inner moons, and dozens of distant, irregular satellites discovered through modern sky surveys.
The total rose sharply in the 21st century as astronomers used sensitive digital cameras to find tiny objects orbiting far from Jupiter. In February 2023, three newly announced moons brought the known total to 95. Many of these satellites are only a few kilometres across and have elongated orbits, suggesting that they are captured asteroids or remnants of earlier collisions.
The number is easy to confuse with older counts. Jupiter had 79 known moons in 2018, and later discoveries raised the total. “Confirmed” is also important: astronomers may detect possible objects, but a moon is counted officially only after follow-up observations establish its orbit. The count can therefore change as new satellites are found and confirmed.
