Saturn's moon Janus -- Janus is a moon of Saturn discovered by the French astronomer Audouin Dollfus in 1966. Dollfus is credited with the discovery of Janus but it's not really certain whether the object he saw was Janus or Epimetheus and his observations led to a spurious orbit (Walker discovered it independently but his telegram arrived a few hours after Dollfus'). Larson and Fountain determined in 1978 that there are in fact two moons sharing one orbit. This was confirmed in 1980...

Saturn's moon Epimetheus -- Epimetheus is a moon of Saturn that was probably first observed by Walker and Audouin Dollfus in 1966 when they discovered Janus, but the situation was confused since Janus is in a very similar orbit and so Walker officially shares the discovery of Epimetheus with Fountain and Larson who showed in 1978 that there were two satellites involved. The situation was clarified in 1980 by Voyager 1. Epimetheus and Janus are "co-orbital". Janus' orbital radius from...

Saturn's moon Prometheus -- Prometheus [pra-MEE-thee-us] is the third of Saturn's known satellites. It was discovered from photographs taken by Voyager during its encounter with Saturn by S. Collins and others. Prometheus acts as a shepherd satellite for the inner edge of Saturn's F Ring. The moon is extremely elongated about 145 by 85 by 62 kilometers (90 by 53 by 39 miles) in diameter. It has a number of ridges and valleys on its northern side. Several craters about 20...
