This is an image of Helene.
Helene was discovered on
February 29, 1980, by
Pierre Laques and Raymond Despiau of the Pic du Midi Observatory, France,
and J. Lecacheux from the Meudon Observatory, France. Their discovery was
made using ground-based observations with a 1-meter telescope of
Pic-du-Midi and a Lallemand electronographic camera. Lacques and
Lecacheux were part of the team which confirmed the discovery a
few months later when photographs of Helene were returned from the Voyager spacecraft.
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.
