Saturn's rings are made up mostly of ice particles, with a smaller amount of rock. These particles range in size from dust grains to boulders. The rings are incredibly thin, only a few kilometers thick, but they extend outward for hundreds of thousands of kilometers.

The intricate structure of Saturn's rings, with its many ringlets, is caused by the gravitational pull of Saturn's moons. These moons create gaps and waves in the rings, shaping them into the complex patterns we see today.
