Actually I think there is one other non planetary object that is known to have a ring but I can’t remember the name of it right now.

And this is why asteroids and comets should be segregated. First you get a comet with a ring, then you get an asteroid with a tail. Then you’ll have objects with tail rings, ring tails, ...it’ll be complete chaos!

Well, what makes a comet a comet? The orbit is elliptical, and it gets the tail flowing out from it as it travels close to the sun. An identical object in a circular orbit far from the sun would never have the tail so it really could never be called a comet.

An asteroid is only an asteroid because it is in a circular orbit around the sun. Orbiting any other body, it would be called a moon of that body. Diemos and Phobos are both tiny rocky objects that really look a lot like asteroids. Some of the moons of Jupiter and Saturn are icy objects that probably would be comets if they were in the right kind of orbits.

Chiron is a lot like Pluto but orbits much closer to the sun. It might have been termed a planet for a while had it been discovered sooner. And any of these objects would be called comets if they passed closer to the sun.

Many find this hard to believe, but Comet-asterrhoid hybrids are merely Gamera's dingleberries.

Well it's spherical and surrounded by a ring, but also accompanied by longitudinal gravitational spikes and an overall central foundation, presumably an asteroidal rocky core. The system itself is exhibiting unusual velocity components, and there seems to be associated electromagnetic frequencies of non-normal strength characteristics.
