decade, Warner reviewed and recalibrated the original data set and determined a period of at least hours with an amplitude of more than (). With such a long period, Camelia is a slow rotator. While the slowest rotators have periods above 1000 hours, the vast majority of asteroids have a much shorter rotation period of 2.2 to 20 hours. Diameter and albedo According to the surveys carried out by the Japanese Akari satellite, the Infrared Astronomical Satellite IRAS, and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer (WISE), Camelia measures (), () and () kilometers in diameter, and its surface has an albedo of (), () and (), respectively. The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0357 and a diameter of 73.63 km based on an absolute magnitude of 10.71. Over the course of a few years, the WISE team has also published several smaller mean-diameters of (), () and () with corresponding albedos of (), () and ().
