Rings of orbiting ice crystals encircle all giant planets in our solar system: Jupiter, Saturn, Uranus and Neptune. Now a much smaller planetoid — an object too small to qualify for planet status — can join them on the list of ringed objects. It is the first time rings have been found around such a small object.
