1517 Beograd, provisional designation 1938 FD, is an asteroid from the outer region of the asteroid belt, about 36 kilometers in diameter. It was discovered by Serbian astronomer Milorad B. Protić at Belgrade Astronomical Observatory on 20 March 1938.[11]
The asteroid orbits the Sun at a distance of 2.6–2.8 AU once every 4 years and 6 months (1,636 days). Its orbit shows an eccentricity of 0.04 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 6.9 hours[9][10] and an albedo between 0.04 and 0.05, according to the space-based surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the Wide-field Infrared Survey Explorer and subsequent NEOWISE mission.[6][7][8]
The X-type asteroid is classified as a member of the Padua family, an asteroid family at least 25 million years old, consisting of mostly X-type asteroids, that were previously associated to 110 Lydia, the namesake of the Lydia family. Together with the Agnia family, the Padua family is the only other family to have most of its members in a nonlinear secular resonance configuration with more than 75% of its members in a z1 librating state.[4][5]
The minor planet was named by the discoverer in honor of his native city and the capital of his country, Belgrade.[2]
