Icy Chariklo asteroid has ring system

The asteroid Chariklo has been confirmed as the smallest object in the Solar System to display a ring system.
Encircling bands of material are more usually associated with the giant planets, such as Saturn and Uranus.
Chariklo may be just 250km wide but observations made when it passed in front of a distant star reveal the presence of two distinct rings.

First Ring System Around Asteroid

Observations at many sites in South America, including ESO's La Silla Observatory, have made the surprise discovery that the remote asteroid Chariklo is surrounded by two dense and narrow rings. This is the smallest object by far found to have rings and only the fifth body in the Solar System - after the much larger planets Jupiter, Saturn, Uranus and Neptune - to have this feature. The origin of these rings remains a mystery, but they may be the result of a collision that created a disc of debris. The new results are published online in the journal Nature on 26 March 2014.
