Claim CE240:
Saturn's rings are unstable. They gradually drift outward, and disruption from bombardment could mean that they could not last more than 10,000 years. The rings cannot be billions of years old.Source:

Response:
- Saturn's rings may be less than 100 million years old (Cuzzi and
Estrada 1998). However, that says nothing about the age of the
planet. The rings could have formed when Saturn captured a small moon
that fell within the Roche limit (the distance below which moons will
be pulled apart by tidal forces). This could have happened any time in
Saturn's history.
- Saturn's moons shepherd the particles that make up the rings, preventing them from drifting and maintaining the gaps between the rings. This shepherding may allow the rings to be much older than 100 million years. (However, the color of the rings suggests not much more than 100 million years' worth of accumulated dust.)
