To humans, the ring system obviously stands out (although it's not the only local body with a ring system). Some say Saturn was influential in the early formation of the solar system and may have been responsible for forcing another planet of orbit, a planet now wandering space on its own.
Hmm looked up the core's of Jupiter and Saturn. Recent guesses say Jupiter has a solid core 10 to 20 times as big as Earth, while Saturn's solid core is only about the size of Earth. And Saturn is mostly gas, same as Jupiter, Neptune, and Uranus.
