Helene

Helene was discovered by the French astronomers Pierre Laques, Raymond Despiau and J. Lecacheux on February 29, 1980. Even though Helene is so far away, they were able to make their discovery at an observatory in France using a telescope and electronographic camera. A few months later, P. Laques and J. Lecacheux, along with the other members of the Voyager team, confirmed the discovery of Helene with pictures taken from space.

Helene is the 6th farthest moon from Saturn, with a standoff distance of 377,400 km. Helene is one of the small moons, and is just 18 x 15 km (12 x 10 miles) in size. Its dimensions make Helene about the size of a medium city.

The surface features can just barely be distinguished in this image. Nevertheless, as a small moon, details about the composition and structure of the moon are unknown.
