Telesto: Companion of Tethys

CICLOPS has released a new low-resolution view of Telesto, the leading trojan of Tethys. The Saturnian system is unique for having sets of co-orbital satellites. Janus and Epimetheus swap orbits every few years. Other satellites revolve around the L4 and L5 Lagrange points of Dione and Tethys. Helene and Polydeuces are leading and trailing trojans of Dione, respectively. Telesto and Calypso are leading and trailing trojans of Tethys, respectively. The resolution on Telesto in this image is 7 km/pixel.
