Telesto is co-orbital with Tethys, residing in Tethys' leading Lagrangian point (L4). The moon Calypso resides in Tethys' trailing Lagrangian point (L5).
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.
