 Next were the Saturnian moons Epimetheus and Janus, observed in 1966.These two moons share the same orbit, and the resulting confusion over their status was not resolved until the "Voyager 1" flyby in 1980.Most of the remaining inner satellites were discovered by spacecraft "Voyager 1" and "Voyager 2" during their flybys of Jupiter (1979), Saturn (1980), Uranus (1986) and Neptune (1989).
