Document Summary
What are saturn"s rings like: the rings aren"t illuminated by saturn, they are illuminated by the sun because. How do other jovian ring systems compare to saturn"s: all four jovian planets have ring systems, others have smaller, darker ring particles than saturn. !1: small moons have no geological activity, they aren"t round and were mostly captured later in life, medium sized moons were geologically active in the past and are round. Tuesday, november 17, 2015: large moons have ongoing geological activity, medium and large moons. Have substantial amounts of ice, because the planets are beyond the frost line. Circular orbits in some direction as planet motion: small moons. These are far more numerous than the medium and large moons. They do not have enough gravity to be spherical. Why are jupiter"s galilean moons so geologically active? (io, europa, ganymede, Io is the most volcanically active body in the solar system. Volcanic eruptions continue to change its surface.
