Epimetheus, a nonspherical body measuring about 89 mi (144 km) by 67 mi (108 km) by 61 mi (98 km), is one of Saturn's 48 confirmed natural satellites. It was discovered in 1966 and photographed in 1980 by the Voyager 1 probe. Epimetheus and another moon, Janus, are co-orbital, meaning that they share nearly the same orbit. About every fourth year, the lower, faster satellite overtakes the other and is boosted into the higher orbit. After what mythological figure is Epimetheus named?
