The Cosmic Collision That Formed Saturn’s Rings
SMRTR summary
Computer simulations by SETI Institute researchers suggest Saturn's rings formed through a cosmic collision involving Titan and another moon hundreds of millions ago. When a hypothetical extra moon merged with a smaller proto-Titan, the collision created debris that became Hyperion while destabilizing other nearby moons, sending their fragments inward to form Saturn's iconic rings. This theory explains why Saturn's rings are relatively young and why Titan has an unusual eccentric orbit with few impact craters on its surface.
