1461 Jean-Jacques, provisional designation 1937 YL, is a metallic asteroid from the outer region of the asteroid belt, about 33 kilometers in diameter. It was discovered by French female astronomer Marguerite Laugier at Nice Observatory in southern France on 30 December 1937.[9]
The metallic M-type asteroid orbits the Sun at a distance of 3.0–3.3 AU once every five and a half years (2,020 days). Its orbit shows an eccentricity of 0.05 and is tilted by 15 degrees to the plane of the ecliptic. It has a rotation period of 16.6 hours[8] and a geometric albedo of 0.10–0.27 according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.[4][5][6][7]
The minor planet was named after Jean-Jacques Laugier, the son of the discoverer.[2]
