[2] This asteroid orbits the Sun in the middle main-belt at a distance of 1.8–3.3 AU once every 4 years and 1 month (1,487 days).

[3][10] In September 2007, Australian astronomers Collin Bembrick and Julian Oey independently obtained two rotational lightcurves of Mavis.

These well-defined lightcurves gave a rotation period of 6.1339 and 6.1508 hours with a brightness variation of 0.50 and 0.53 magnitude, respectively (U=3/3).

[4][5][6][7] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.3320 and a diameter of 12.10 kilometers based on an absolute magnitude of 11.4.
