Quaoar Had One ‘Impossible’ Ring, Then Astronomers Found Two - The New York Times

Earlier this year, astronomers announced that a tiny world beyond Neptune with a diameter about one-third that of Earth's moon possessed a Saturn-like ring that should not be there. It now turns out that there are two such "impossible" rings.

"It was a big surprise," said Chrystian Luciano Pereira, a doctoral student at the National Observatory in Brazil who led the observations of the world, known as Quaoar. "This implies that Quaoar is a more complex system than we initially thought."
