1554 Yugoslavia, provisional designation 1940 RE, is a stony asteroid from the middle region of the asteroid belt, about 17 kilometers in diameter. It was discovered by Serbian astronomer Milorad Protić at Belgrade Astronomical Observatory, Serbia, on 6 September 1940.[10]
The asteroid is a member of the Eunomia family, a large group of S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun at a distance of 2.1–3.1 AU once every 4 years and 3 months (1,547 days). Its orbit shows an eccentricity of 0.20 and is tilted by 12 degrees to the plane of the ecliptic. It has a well-defined rotation period of 3.89 hours, measured by several photometric light-curve observations.[7][8][9] Based on measurements by the Japanese Akari satellite and the Wide-field Infrared Survey Explorer, the body's albedo is inconclusive – ranging from 0.07 to 0.27 – while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21, typical for stony asteroids.[3]
The minor planet was named for the former country of Yugoslavia.[2]
