Jupiter has 67 known moons, although 17 of them are awaiting official names. More are discovered with every space probe we send there. It is likely that there are more not yet identified. The most recent are extremely small.
The first four of Jupiter's moons, Io, Europa, Ganymede, and Callisto were discovered by Galileo in 1610. Since then 59 additional moons have been discovered, the last, desigâ¦nated J23, was discovered in 2003.
