: Huge 98-foot-wide asteroid to travel between Earth and Moon Chariklos rings have crisp edges, a feature typically caused by the gravitational effects of a small embedded moon or moons. Its likely that Chariklo has at least one small moon still waiting to be discovered, Braga-Ribas said. Chariklos inner ring is 4.3 miles (7 km) wide and the outer ring is 1.9 miles (3 km) wide. The bands are separated by a 5.6 mile (9 km) wide gap. It was quite amazing to realize that we were able not only to detect a ring system, but also pinpoint that it consists of two clearly distinct rings, astronomer Uffe Grae Jorgensen, with the University of Copenhagen in Denmark, said in a statement. The origin of the rings is not known, but scientists suspect they formed after another body crashed into Chariklo, forming a debris disk of icy particles. -Reuters
