where are saturn rings made of
AlthoughÂ­ Jupiter, Uranus and Neptune have rings of their own, none are as spectacular as Saturn's. Saturn's rings are also one of the great mysteries in space. But as our spacecraft edge closer than ever to the rings, we're getting a more complete picture of what they're made of and how they came to exist. Saturn has six main rings, each composed of thousands of tiny ringlets. The rings are huge -- the biggest ones spanning 170,000 miles (273,588 km) in diameter. They are, however, proportionately very thin -- only about 650 feet (200 meters) thick. They aren't solid, as they appear from Earth, but are instead made up of floating chunks of water ice, rocks and dust that range in size from specks to enormous, house-sized pieces that orbit Saturn in a ring pattern.
