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.
Between the top of Jupiter's clouds and the orbit of the closest moon; the ring also orbits just above Jupiter's equator. It may be in part debris from Io's violent volcanoes, and dust from the breakup of the tiny moons Tethys and Adrastea, both so close to Jupiter they are under great tidal stress. Ice particles like Saturn's rings cannot exist to close to hot Jupiter, which gives back into space twice the energy it gets from the Sun.
