Summary

Story summary

Saturn's rings consist mainly of water ice (about 99%), with dust, making them highly reflective.
Particles in the rings move at speeds up to 45,000 mph.
They disappear from Earth every 14 years when viewed edge-on, with the last in March 2025.
Ring rain gradually dissipates the rings, which could vanish in 100 to 300 million years.
The E ring is replenished by icy particles from Enceladus.
