Methone information Average distance from Saturn: 194440 km (0.0013 AU) Equatorial radius: 1.5 km (Diameter: 3 km) Siderial orbit period (length of year): 1.009573975 earth days Orbital eccentricity: 0.0001 Orbital inclination to ecliptic: 0.007 degrees		Methone, Saturn XXXII
Methone Methone is a very small natural satellite of Saturn lying between the orbits of Mimas and Enceladus. It was discovered by Sébastien Charnoz, member of Cassini imaging scientists team led by Carolyn C. Porco, et al. in 2004, and given the temporary designation S/2004 S 1. Methone is also named Saturn XXXII. Methone is visibly affected by a perturbing mean longitude resonance with the much larger Mimas. This causes its osculating orbital elements to vary with an amplitude of about 20 km in semi-major axis, and 5° in longitude on a timescale of about 450 days. Eccentricity also varies on different timescales between 0.0011 and 0.0037, and inclination between about 0.003° and 0.020°. The name Methone was approved by the IAU Working Group on Planetary System Nomenclature on January 21, 2005. It should be officially approved at the IAU General Assembly in 2006. Methone was one of the Alkyonides, the seven beautiful daughters of the Giant Alkyoneus.
