    1550 Tito, provisional designation 1937 WD, is a stony asteroid and somewhat slow rotator from the inner regions of the asteroid belt, about 12 kilometers in diameter. It was discovered by Serbian astronomer Milorad B. Protić at the Belgrade Astronomical Observatory, Serbia, on 29 November 1937.[10]

    The S-type asteroid orbits the Sun at a distance of 1.8–3.3 AU once every 4 years and 1 month (1,483 days). Its orbit shows an eccentricity of 0.31 and is tilted by 9 degrees to the plane of the ecliptic. It has a relatively long rotation period of 54.2 hours[7][9] and an albedo in the range of 0.20–0.26, according to the surveys carried out by the Japanese Akari satellite and the Wide-field Infrared Survey Explorer and subsequent NEOWISE mission.[4][5][6]

    It was named in honour of Josip Broz Tito (1892–1980), leader of the Yugoslavian resistance during the World War II, early enthusiast of the United Nations, and president of former Yugoslavia.[2]
