Albiorix
Albiorix is a prograde irregular satellite of Saturn. Albiorix is the largest member of the Gallic group of irregular satellites. It was named in August 2003 for Albiorix, "a Gallic giant who was considered to be the king of the world". Given the similarity of the orbital elements and the homogeneity of the physical characteristics with other members of the Gallic group, it was suggested that these satellites could have a common origin in the break-up of a larger moon. Varying colours revealed recently suggest a possibility of a large crater, leading to an alternative hypothesis that Erriapus and Tarvos could be fragments of Albiorix following a near-break-up collision with another body.
