Background Information

    Jupiter is the most massive planet in our solar system. With four large moons and many smaller moons, it forms a kind of miniature solar system. Jupiter resembles a star in composition, and if it had been about 80 times more massive, it would have become a star rather than a planet.

    On Jan. 7, 1610, using his primitive telescope, astronomer Galileo Galilei saw four small "stars" near Jupiter. He had discovered Jupiter's four largest moons, now called Io, Europa, Ganymede and Callisto. These four moons are known today as the Galilean satellites.
