Ring of ice. Ring of ice. Round your Quaoar
Well, let me be the first to admit that I did not believe that I would live to see the day that a ring of dust would be discovered around a piece of crap floating way out there. This discovery will undoubtedly alter the fabric our society profoundly. (Still trying to figure out why astrophysics is a career path and not a hobby). NASA declined to mention that they are investigating the rings for signs of intelligent life.
Anyway, there is one inner planet with its own ring system: Earth, surrounded by junk.
