Saturn has the most extensive ring system in the Solar System. Sitting in the region of space spanning 7000 to 80 000 km above the planet's equator, these rings are mostly composed of particles of water ice contaminated with traces of rocky material, varying in size from dust grains to mountain-sized chunks, laced throughout.
