Observations at many sites in South America, including the European Southern Observatory's (ESO) La Silla Observatory, have made the surprise discovery that two dense and narrow rings surround the remote asteroid Chariklo. 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 disk of debris.

That is an incredibly old x-ray.
