 Previous observations by Richard Binzel in May 1984 gave a similar period of 5.79 hours and an amplitude of 0.93 magnitude ().According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, "Aquilegia" measures between 11.288 and 18.93 kilometers in diameter and its surface has an albedo between 0.139 and 0.389.The "Collaborative Asteroid Lightcurve Link" adopts the results obtained by IRAS, that is, an albedo of 0.1572 and a diameter of 17.75 kilometers based on an absolute magnitude of 11.38.
