 The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0469 and a diameter of 80.91 kilometers based on an absolute magnitude of 9.4.Photometric observations of "Telamon" by Stefano Mottola from August 1995 were used to build a lightcurve rendering a rotation period of 11.2 hours with a brightness variation of in magnitude ().In October 2010, another observation by Robert Stephens at the Goat Mountain Astronomical Research Station in California gave a period of 16.975 hours ().
