[2][6] Sy orbits the Sun in the central main-belt at a distance of 2.2–3.0 AU once every 4 years and 1 month (1,503 days).
[5] According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Sy measures 13.998 kilometers in diameter, and its surface has an albedo of 0.157,[4] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 12.39 kilometers with on an absolute magnitude of 11.9.
[3] In March 2012, photometric observations at the Oakley Southern Sky Observatory (E09), Australia, included this asteroid as a target.
[3] This minor planet was named after Frédéric Sy, who worked as a human orbit computer and as an assistant astronomer at Algiers and Paris Observatory, respectively.
At Algiers Observatory, he observed asteroids and comets and was the first to discoverer a numbered minor planet, 858 El Djezaïr, in 1916.
