Methone (moon)
Cassini image of Methone's leading side taken on 20 May 2012. Its unusually smooth surface is likely from the accumulation of dust | |

Methone /mɛˈθoʊniː/ is a small, egg-shaped natural satellite of Saturn that orbits out past Saturn's main ring system, between the orbits of Mimas and Enceladus. It was discovered in 2004, though it was not until 2012 that it was imaged in detail by the Cassini spacecraft.
