Epimetheus v4- SOLD

Epimetheus: An inner satellite of Saturn. It is also known as Saturn XI. It is named after the mythological Epimetheus, brother of Prometheus.  Epimetheus occupies essentially the same orbit as the moon Janus. Epimetheus and Janus are co-orbital: Janus's mean orbital radius from Saturn is as of 2006 only 50 km less than that of Epimetheus, a distance smaller than either moon's mean radius. In accordance with Kepler's laws of planetary motion, the closer orbit is completed more quickly, but only by about 30 seconds. Each day the inner moon is an additional ¼° farther around Saturn than the outer moon. As the inner moon catches up to the outer moon, their mutual gravitational attraction boosts the inner moon's momentum and saps the outer moon's momentum. With this added momentum, the inner moon's distance from Saturn and orbital period are increased, and the outer moon's are decreased. The timing and magnitude of the momentum exchange is such that the moons "trade" orbits, never approaching closer than about 10,000 km. The exchange takes place about once every four years; the last close approaches occurred on January 21, 2006, and in 2010, when Janus's orbital radius increased by ~20 km, while Epimetheus's decreased by ~80 km; Janus's orbit is less affected because it is four times more massive than Epimetheus. As far as it is currently known, this arrangement is unique in the Solar System.
