1564 Srbija, provisional designation 1936 TB, is a dark asteroid from the outer region of the asteroid belt, about 39 kilometers in diameter. It was discovered by Serbian astronomer Milorad Protić at the Belgrade Observatory in Serbia, on 15 October 1936.[8]
The dark X-type asteroid orbits the Sun at a distance of 2.5–3.8 AU once every 5 years and 8 months (2,061 days). Its orbit shows an eccentricity of 0.20 and is tilted by 11 degrees to the plane of the ecliptic. It has a rotation period of 9.1 hours[6] and an alternative observation that gave a period of almost 30 hours, respectively.[7] It has a very low albedo between 0.04 and 0.05, according to the surveys carried out by the space-based Akari and WISE satellites.[4][5]
The minor planet was named in honour of the now sovereign state of Serbia.[2]
