Detailed explanation-1: -By most counts, Jupiter has between 80 and 95 moons, but neither number captures the complexity of the Jovian system of moons, rings and asteroids. The giant planet commands thousands of small objects in its orbit.
Detailed explanation-2: -Jewitt. Since 2003, 16 additional moons have been discovered but not yet named, bringing the total number of known moons of Jupiter to 67. Though the Galilean moons were named shortly after their discovery in 1610, the names of Io, Europa, Ganymede and Callisto fell out of favor until the 20th century.
Detailed explanation-3: -They are called the Galilean moons or satellites after Italian astronomer Galileo Galilei, who first observed them in 1610.
Detailed explanation-4: -The German astronomer Simon Marius claimed to have seen the moons around the same time, but he did not publish his observations and so Galileo is given the credit for their discovery. These large moons, named Io, Europa, Ganymede, and Callisto, are each distinctive worlds.
