1714 Sy, provisional designation 1951 OA, is a stony asteroid from the middle regions of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 25 July 1951, by French astronomer Louis Boyer at Algiers Observatory in Algeria, North Africa, and named after French astronomer and orbit computer Frédéric Sy.
Sy orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 1 month (1,503 days). Its orbit has an eccentricity of 0.15 and an inclination of 8° with respect to the ecliptic. It was first identified as 1949 YM at Goethe Link Observatory in 1948, extending the body's observation arc by 3 years prior to its official discovery observation at Algiers.
Classified by PanSTARRS' large-scale survey, Sy is a L-type asteroid, a rare subtype which falls into the broader stony S-complex.
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, 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.
