Saturn's Rings (Edge View)

282,000 km wide but thinner than a razor blade in proportion/Deep Space

Saturn's rings span about 282,000 km in diameter but are only about 10-30 meters thick in most places. If you scaled the rings down to the diameter of a football field, they would be about 10,000 times thinner than a razor blade. They are composed of billions of particles ranging from dust grains to house-sized boulders, all made mostly of water ice. The rings may be only 100-400 million years old, making them younger than the dinosaurs.
