It was discovered by Brett Gladman, John J. Kavelaars and colleagues in 2000, and given the temporary designation S/2000 S 10.[5][6] It was named Erriapo in August 2003[7] after Erriapus, a giant in Gaulish mythology; the name was changed from dative Erriapo to nominative Erriapus per IAU conventions in late 2007.[8][9] Erriapus is about 10 kilometres in diameter, and orbits Saturn at an average distance of 17,3 Gm in 871 days. As a member of the Gallic group of irregular satellites, which share similar orbital characteristics and a light-red colour, Erriapus is hypothesized to have its origin in the break-up of a common progenitor of the group,[4][10] or to be a fragment of its largest member, Albiorix.[11] References1. ^Discovery Circumstances (JPL) 2. ^Mean orbital parameters from JPL 3. ^1 Scott Sheppard pages 4. ^1 Grav, T.; Holman, M.
