Moons and rings of jovian planets : 11. 2, 11. 3. A wealth of worlds: satellites of ice and rock - 11. 2. The jovian planets are surrounded by 150 moons in orbit, which range from 3 size categories such as: Small moons are most likely captured moons or asteroids individual jovian planets. Jupiter"s galilean moons are extremely geologically active *** Io: the most volcanically active world in the solar system, due to tidal heating from jupiter heating up the interior of the moon. Due to io"s unique elliptical orbit due to orbital resonance from nearby moons and jupiter, the tidal forces on io are extremely strong, as if being pulled on by all directions and thus create tremendous amounts of energy. Europa: the water world, ice water covers the surface of europa and there is strong evidence of a sub- surface of liquid water. Ganymede: is the largest moon in the solar system and similar to europa, is covered by ice water.
