It orbits the Sun in the inner main-belt at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,220 days).
[10] Between 2009 and 2013, several rotational lightcurves for this asteroid were obtained from photometric observations at the Palomar Transient Factory and the Hunters Hill Observatory, as well as by astronomers Eric Barbotin and Raoul Behrend.
Lightcurve analysis gave a rotation period between 11.48 and 12.20 hours with a brightness variation between 0.21 and 0.25 in magnitude (U=2/2/2).
[6][7][8] According to the survey carried out by the Japanese Akari satellite, Chacornac measures 10.3 kilometers in diameter and its surface has an albedo of 0.224,[5] while observations by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission gave a diameter of 8.4 kilometers and a high albedo of 0.36.
[4] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by AKARI and assumes an albedo of 0.24 – derived from 8 Flora, the family's largest member and namesake – and calculates a diameter of 9.9 kilometers with an absolute magnitude of 12.2.
