Asteroid with ring system discovered

A 250km-wide rock known as Chariklo is the smallest known object to feature a ring system.
Up until now rings were thought to be exclusive to larger bodies such as the gas giant planets Saturn and Uranus, but astronomers working from telescopes in South America have this week announced the discovery of a tiny asteroid with what appear to be two distinct rings.

"Our best guess for the origin of the rings is that there was a collision on Chariklo and that this collision injected a disc of material around the body," said astronomer Bruno Sicardy.
The two rings measure 7km and 3km in width with a 9km gap between them. While the asteroid's current path places it just beyond the orbit of Saturn it is believed that it would have originally formed in the outer solar system.

Astronomers were able to see the rings by observing the asteroid as it passed in front of a distant star.

So would the moon be orbiting between the rings having cleaned out that central corridor? How come there is no evidence of the moon in the occultation data? Observations of the occultation of asteroid CharikloThis video shows what happened when the asteroid Chariklo passed in front of a star. As well as the expected drop in brightness when the asteroid blocked the light of the star two smaller dips were seen, before and afterwards, caused by the presence of a double ring.Credit: ESO/Felipe Braga Ribas/M.

How come there is no evidence of the moon in the occultation data? Because moons orbit around their primary, in other words they are constantly moving. The chances of a small moon being in exactly the correct point in it's orbit to occult the star are quite low.

Astronomy is the best cinema you can get. Period.

Thats not conclusive evidence of rings. The asteroid may have two or more moons that happened to be in the correct spatial alignment at the right time. Just saying.

Anything is possible but that is highly improbable. There are two rings which means 4 occlusions so there would have to be 4 moons, all lined up perfectly, to get your results. What do you think is more likely? Plus, I am sure, when a team of professionals considers all the data from the various instruments involved, that they are pretty sure they are looking at rings, two of them, around the asteroid..

Impressive find! Perhaps in the future tech will have reached a stage where we can send thousands of tiny exploratory robotic ships with cameras to all these exotic worlds to gather data and take photos.

That would be great. Or even if those robots could attach to one and navigate it back to Earth for the purpose of 's t u d y' lol.

You don't know what you are talking about. Just saying. Anything is possible but that is highly improbable. There are two rings which means 4 occlusions so there would have to be 4 moons, all lined up perfectly, to get your results. Not only that but you would have to have two pairs of moons sharing only two orbits. The pairs would have to be 180o from each other. This is a highly unstable situation. The chances of finding one pair... [More]

Awesome find.i bet there are other asteroids with rings around them

Awesome find.i bet there are other asteroids with rings around them I'd bet you are right sir. Cheers to the folks that are finding them, the geniuses that created the tools to find them and the guys with 40 pound heads that think this stuff up and then go look for it. We are a helluva a species aren't we?
