1807 Slovakia, provisional designation 1971 QA, is a stony asteroid from the inner regions of the asteroid belt. It was discovered on 20 August 1971 by Slovak astronomer Milan Antal at Skalnaté pleso Observatory near Tatranská Lomnica in the High Tatras mountains.[7]
The S-type asteroid orbits the Sun at a distance of 1.8–2.6 AU once every 3 years and 4 months (1,213 days). It has an albedo of 0.20–0.31.[3][4]
The 9-kilometer sized asteroid has an exceptionally long rotation period of 308 hours.[5] Previous observations made by the Geneva observatory in 2003 gave a provisional period of 1.9 days or about 46 hours.[6]
It was named in honor of the now independent state of Slovakia (Slovak Republic), the country where the discovering observatory is located. At the time Slovakia was still part of the socialistic republic of Czechoslovakia that was formed after World War I and lasted until the end of the Cold War (also see 2315 Czechoslovakia).[2]
