Telesto Template:IPAc-en is a moon of Saturn. It was discovered by Smith, Reitsema, Larson and Fountain in 1980 from ground-based observations, and was provisionally designated Template:Nowrap.Template:Sfn In the following months, several other apparitions were observed: Template:Nowrap,Template:Sfn Template:Nowrap,Template:Sfn and Template:Nowrap.Template:Sfn
In 1983 it was officially named after Telesto of Greek mythology.Template:Efn It is also designated as Template:Nowrap or Tethys B.
Telesto is co-orbital with Tethys, residing in Tethys's leading Lagrangian point (Template:L4). This relationship was first identified by [[#Template:SfnRef|Seidelmann et al.]] in 1981.Template:Sfn Another moon, Calypso, resides in the other (trailing) Lagrangian point of Tethys, 60 degrees in the other direction from Tethys. The Saturnian system has two additional trojan moons.
Exploration
The Cassini probe performed a distant flyby of Telesto on October 11, 2005. The resulting images show that its surface is surprisingly smooth, devoid of small impact craters.
