  • Helene is a moon of Saturn. It was discovered by Pierre Laques and Jean Lecacheux in 1980 from ground-based observations at Pic du Midi Observatory, and was designated S/1980 S 6. In 1988 it was officially named after Helen of Troy, who was the granddaughter of Cronus in Greek mythology. The moon is also designated Saturn XII, a number which it received in 1982, under the designation Dione B, because it is co-orbital with Dione and located in its leading Lagrangian point. It is one of four known trojan moons. Wikipedia
