Astronomers believe that Saturn’s rings are made of water, ice, and rock.
This icy matter can range from the size of a tiny grain of sand to bigger than a boulder, over 30 feet (9 meters) across.
The particles probably came from passing comets or moons that got too close to Saturn and were broken up.
The space debris was then caught in the planet’s force of gravity.
Or perhaps the rings are composed of remnants of the Sun’s explosion into adulthood, particles of solar matter that never coalesced into moons or planets.
