1554 Yugoslavia
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.〔
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.〔〔〔 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 the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21, typical for stony asteroids.〔
The minor planet was named for the former country of Yugoslavia, which existed between the end of World War I and the end of the Cold War (1918–1992) and was succeeded by the Federal Republic of Yugoslavia, also known as Serbia and Montenegro.〔
