Is there anything in nature that is perfectly circular? Perfect circles exist in math only.

Just for a comparison, and I actually wonder about it: Celestial bodies revolve around other objects due to gravity, does the same apply to Saturn's rings too (or is it just like Saturn's atmosphere)?

I was looking for an example for a circular orbit. Saturn's rings are a set of large number of bodies and they together form a perfect circular orbit.

They don't have one orbit, just individual orbits which are not perfect circles. The average of the individual orbit is closer to the circle but not a perfect circle either.Saturn's rings are a set of large number of bodies and they together form a perfect circular orbit.

Thanks for the information, and is gravity responsible for their revolution as it is for the revolution of other celestial bodies?They don't have one orbit, just individual orbits which are not perfect circles. The average of the individual orbit is closer to the circle but not a perfect circle either.
