1574 Meyer, provisional designation 1949 FD, is a dark, carbonaceous asteroid from the outer region of the asteroid belt, about 59 kilometers in diameter. It was discovered by French astronomer Louis Boyer at the Algerian Algiers Observatory in northern Africa, on 22 March 1949.[7]
The C-type asteroid orbits the Sun at a distance of 3.4–3.7 AU once every 6 years and 8 months (2,435 days). Its orbit shows an eccentricity of 0.04 and is tilted by 14 degrees to the plane of the ecliptic. It has a rotation period of 12.6 hours[6] and a low albedo of 0.030–0.04, as observed by the space-based Akari and WISE missions.[3][4]
The asteroid was named after French astronomer M. Georges Meyer (b.1894), director of the discovering Algiers Observatory.[2]
