1714 Sy, provisional designation 1951 OA, is an asteroid from the main-belt, about 17 kilometers in diameter. It was discovered by French astronomer Louis Boyer at the North African Algiers Observatory in Algeria on July 25, 1951. The asteroid orbits the Sun at a distance of 2.2–3.0 AU once every 4.11 years (1,503 days). It has a geometric albedo of 0.11.[1]
It is named after Frédéric Sy, who worked as an orbit computer and an assistant astronomer at Paris Observatory and Algiers Observatory, respectively. At Algiers Observatory, he observed asteroids and comets and was the first to discover a numbered minor planet, 858 El Djezaïr, in 1916.[2]
