Irregular prograde groups of satellites of Saturn: Gallic (red) and Inuit (blue)

Albiorix is a non-spherical moon of Saturn. It was found by Holman, et al. in 2000, and given the designation S/2000 S 11.

Albiorix is the biggest member of the Gallic group of non-spherical moons.

It was named in August 2003 from one of the Celtic names for the god of tribal unity, better known as Toutatis.

Albiorix orbits Saturn at a distance of about 16,000,000 km and its diameter is estimated at 32 kilometers, assuming an albedo of 0.04. A day on Albiorix is 13 hours and 19 minutes long.

The diagram illustrates its orbit in relation to other prograde non-spherical moons of Saturn. The eccentricity of the orbits is represented by the yellow segments extending from the pericentre to the apocentre.

Different colours seen recently suggest a possibility of a big crater, suggesting that Erriapo and Tarvos could be pieces of Albiorix following a near break-up collision with another body.
