Saturn: Moons: Helene

This image of Helene was acquired by the Voyager 2 spacecraft on August 25, 1981.

Helene is referred to as a Trojan satellite because it orbits Saturn in the Lagrange point of the larger moon Dione. Discovered in 1980 during the Earth ring-plane crossing by J. Lecasheux et al., the moon is small and very faint.
