Nomenclature	Permalink

By convention, new Jupiter satellites receive a Gréco-Roman mythological name. For Jupiter satellites more distant than the four principal satellites, and which orbit is in the same direction as the planet receive a name (in Latin) ending in an "a", while those turning in the Jupiter opposite direction (retrograde orbit) receive a name (in Greek) ending in an "e". Themisto is an exception to the rule partly because this satellite is closer to Callisto. __________________

The International Astronomical Union (IAU) has approved the name Herse for the moon Jupiter L discovered on the 27th February, 2003 by B. Gladman, J. Kavelaars, J.-M. Petit, and L.
