Jupiter has several large moons that human astronomers have studied and mapped. The largest, in order from innermost to outermost orbit around the planet, are: 1  Io â Noted for the unique presence of volcanoes. 2  Europa â Noted for its ice-covered surface. 3  Ganymede â Noted for being the largest of all Jupiter's moons. 4  Callisto.
Jupiter's moons. Jupiter has at least 63 moons, which are often named after the Roman god's many lovers. The four largest moons of Jupiter, now called Io, Europa, Ganymede, and Callisto, were discovered by Galileo Galilei himself, and are appropriately known today as the Galilean satellites. Ganymede is the largest moon in our solar system, larger even than Mercury and Pluto.
