Default Rings on Saturn??

"Jo & MickD" wrote in message ...
Why do the rings on Saturn look so perfect ie have perfect looking gaps
around them.
How does this actually happen or work?????????


Gravitational resonance with Saturn's other moons is one of the
primary factors. So something breaks up in Saturn's orbit. For
millions of years you have just a nebulous debris ring. Over time,
debris is tugged on by Saturn's moons, which orbit it in regular
intervals. Over time, the debris particles reach equilibrium orbits
due to this tugging as well as impacts with other debris.

The rings are a result of millions of years this gravitational
tugging, turning chaos slowly into order (giving up potential energy
in the process (i.e. going into lower orbits and sapping some of the
kinetic energy of Saturn's moons), so as not to violate the laws of
thermodynamics).

Hope that helps,
