Janus (Saturn X, S/1966 S 2) is one of the inner [natural satellites|moons]] of Saturn. It was discovered by Audouoin Dollfus on 15 December 1966. However, Jean Teereau had imaged Janus on 29 October the same year, but, did not recognize it as a new body. Janus was named for Janus of Roman mythology.
Janus is co-orbital with Epimetheus in that when Janus' orbit is slightly smaller than that of Epimetheus, over time, Janus will catch up with Epimetheus, as it makes its approach, it is slightly drawn toward Epimetheus adding orbiter energy placing it in a slightly larger orbit, then it will slow down and recede from Epimetheus, and over time Epimetheus will catch up to it. So, they 'swap orbits' so to speak. This occurs about every four years.
Janus in Orbiter[edit]
Janus was first introduced to Orbiter with the release of isaturn.zip in October 2002.
