The tenth of Saturn’s known satellites. It is irregularly-shaped and has a diameter of 29 x 22 x 20 km. Telesto orbits Saturn at a distance of 294,660 km. Telesto is co-orbital with Tethys, residing in Tethys’ leading Lagrangian point (L4). The images taken by the Cassini probe during its distant flyby on October 11, 2005 show that its surface is surprisingly smooth, devoid of small impact craters. Telesto was discovered by B. Smith, H. Reitsema, S. Larson, J. Fountain in 1980 from ground-based observations.
