Janus is a small moon of Saturn that orbits very close to the planet. It's notable because it shares an orbital path with another Saturnian moon called Epimetheus, and the two moons periodically swap positions as they travel around Saturn.

Janus (S X Janus) est un satellite naturel de Saturne.Parce que Janus et Épiméthée partagent pratiquement la même orbite, la confusion régna longtemps sur leurs caractéristiques orbitales ; il est évidemment impossible de réconcilier les observations de deux corps distincts en une seule orbite.
