 Lightcurve analysis gave a rotation period of 8.470 hours with a brightness variation of 0.17 magnitude ().According to the surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, "Gotho" measures between 53.56 and 56.296 kilometers in diameter and its surface has an albedo between 0.008 and 0.045 (without preliminary results).The "Collaborative Asteroid Lightcurve Link" derives an albedo of 0.0469 and a diameter of 51.05 kilometers using an absolute magnitude of 10.4.
