It orbits the Sun in the outer asteroid belt at a distance of 2.4–3.9 AU once every 5 years and 9 months (2,089 days).
[2] The author of the Dictionary of Minor Planet Names, Lutz Schmadel, compiled this citation asking several Russian astronomers including Nikolai Chernykh for further information.
[11] In July 2014, a rather asymmetric bimodal lightcurve, obtained by a collaboration between American astronomers Frederick Pilcher and Andrea Ferrero, gave a more refine rotation period of 10.098 hours with a brightness variation of 0.24 magnitude.(U=3).
[10] According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Aidamina measures between 78.73 and 82.28 kilometers in diameter, and its surface has a low albedo between 0.035 and 0.04 (without preliminary results).
[4][5][6][7] The Collaborative Asteroid Lightcurve Link adopts the results obtained from 17 observations made by IRAS, that is, an albedo of 0.0365 and a diameter of 78.73 kilometers with an absolute magnitude of 9.73.
