It orbits the Sun in the inner main-belt at a distance of 1.7–3.0 AU once every 3 years and 8 months (1,343 days).

[1] A first precovery was obtained at the Australian Siding Spring Observatory in 1975, extending the asteroid's observation arc by 14 years prior to its discovery.

[7] In November 2006, American astronomer Brian Warner obtained a rotational lightcurve from photometric observations taken at his Palmer Divide Observatory in Colorado.

[6] According to the survey carried out by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid measures 4.9 kilometers in diameter and its surface has a high albedo of 0.32,[5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.23 and hence calculates a somewhat larger diameter of 5.3 kilometers with an absolute magnitude of 13.6.

It was founded by the Romans in the 1st century BC on the rivers Sihl and Limmat and was then called Turicum.
