Albiorix (/ˌælbiˈɒrᵻks/ AL-bee-ORR-iks) is a prograde irregular satellite of Saturn. It was discovered by Holman and colleagues in 2000, and given the temporary designation S/2000 S 11.
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." The name is known from an inscription found near the French town of Sablet which identifies him with the Roman god Mars (an interpretatio romana).
Albiorix orbits Saturn at a distance of about 16 million km and its diameter is estimated at 32 kilometers, assuming an albedo of 0.04. The rotation period was measured by the ISS camera of the Cassini spacecraft to 13 hours and 19 minutes.
The diagram illustrates the Albiorigian orbit in relation to other prograde irregular satellites of Saturn. The eccentricity of the orbits is represented by the yellow segments extending from the pericentre to the apocentre.
