[2][13] Edmée orbits the Sun in the middle main-belt at a distance of 2.5–3.0 AU once every 4 years and 6 months (1,658 days).
[13] Edmée is classified as a rare XB-type in the Tholen taxonomy, an intermediary between the X and B type asteroids.
[11][a] In 2013, a much shorter period was derived from a fragmentary lightcurve at the Palomar Transient Factory in California (U=1).
[8] 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, Edmée measures between 23.86 and 27.49 kilometers in diameter, and its surface has an albedo between 0.137 and 0.182.
[4][5][6][7] The Collaborative Asteroid Lightcurve Link adopt the results from IRAS, that is, an albedo of 0.1371 and a diameter of 27.49 kilometers with an absolute magnitude of 10.58.
