It was discovered on 15 October 1936, by Serbian astronomer Milorad Protić at the Belgrade Astronomical Observatory in Serbia. It is named for the country of Serbia. Classification and orbit The C-type asteroid is also classified as an X-type in the Tholen taxonomy. It orbits the Sun in the outer main-belt at a distance of 2.5–3.8 AU once every 5 years and 8 months (2,070 days). Its orbit has an eccentricity of 0.20 and an inclination of 11° with respect to the ecliptic. Srbija's observation arc begins 3 years prior to its official discovery observation with its first identification as 1933 FR 1 at Heidelberg in 1933. Physical characteristics Astronomers Maryanne Angliongto and Milan Mijic at Cal State LA, United States, obtained a rotational lightcurve of Srbija in May 2006. It gave a rotation period of 29.64 hours with a brightness variation of 0.37 magnitude (U=2). In November 2009, photometric observations by James W. Brinsfield at Via Capote Observatory G69, California, gave a shorter period of 9.135 hours with an amplitude of 0.17 (U=3). According to the space-based surveys carried out by the Japanese Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Srbija measures between 29.48 and 43.23 kilometers in diameter, and its surface has an albedo between 0.042 and 0.10. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 37.12 kilometers with an absolute magnitude of 10.88. Naming This minor planet was named in honour of the now sovereign state of Serbia in its transliterated native pronunciation (sr Србија / sr-Latn Srbija). Srbija's discovery in 1936 was the first minor planet discovery made at Belgrade Observatory. The official 1564 naming citation was published by the Minor Planet Center in December 1952 (M.P.C. 844).
