The answers discussed about Uranian ring system (how the planets orbits, how the rings are oriented and how it changes its faces every half of its orbit wrt the Sun [called ring plane crossing]). One of the commenters asked: "Is it possible for planetary rings to be perpendicular to their planet's axial tilt?" to which @ProfRob replied:
the answer is that if the rings are produced by the breakup of a captured satellite, then yes they can be. If the rings are formed at the same time as the planet, then no they can't. Some of Saturn's rings are out of the equatorial plane.
I assumed, he is talking about Phoebe ring which is tilted 27 degrees from Saturn's equatorial plane (and the other rings) [Image for reference]. The other answers also noted the explanation that since it is a result of micrometeorite impact of a former satellite that broke, it followed whatever the orbit that satellite had. OTOH, if the ring was formed together with the planetary system, then the ring should be exactly on the equatorial plane.
So the question is: Are there any ring system other than Phoebe ring that was not formed along with the planet and was a result of a meteorite impact or from a former satellite that broke into a ring? In other words, are there any ring system other than the said example not aligned to the equatorial plane?
