2575 Bulgaria, provisional designation 1970 PL, is a stony asteroid from the inner regions of the asteroid belt, about 7 kilometers in diameter. It was discovered on 4 August 1970, by Russian female astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[5]
Classified as a Sr-subtype in the SMASS taxonomy, the S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 4 months (1,224 days). Its orbit shows an eccentricity of 0.12 and is tilted by 5 degrees to the plane of the ecliptic. It has a rotation period of 8.6 hours[4] and an albedo of 0.24, as assumed by the Collaborative Asteroid Lightcurve Link.[3]
The minor planet was named after the European country Bulgaria. At the time of naming, it was the People's Republic of Bulgaria (1946–1990), a former satellite state of the Soviet Union and member of the Warsaw Pact.[2]
