Introducing Chariklo, the first asteroid-like object discovered with rings.
This is the first time any object besides a Solar System gas giant—Jupiter, Saturn, Uranus, Neptune—has been found to have rings. Chariklo is technically a centaur, one of many centaurs that orbit between Jupiter and Neptune and have both asteroid-like and comet-like properties, which makes them a bit of a mystery. Asteroids and comets are distinguished by where they were formed and what they are made of; Chariklo, the largest of the centaurs, happens to be is more asteroid-like.
