It was discovered on 12 March 1975, by Soviet–Ukrainian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.The E-type asteroid, classified as an EU-subtype in the Tholen taxonomy, is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.6–2.2 AU once every 2 years and 8 months (960 days). Its orbit shows an eccentricity of 0.14 and is tilted by 23 degrees to the plane of the ecliptic. It has a rotation period of 2.813 hours and an assumed, very high albedo of 0.4, which is typical for E-type asteroids of the Hungaria family.In March 2009 the Central Bureau for Astronomical Telegrams announced the discovery of a moon orbiting the asteroid. The satellite measures about 1.4 kilometer in diameter and orbits Litva at distance of 21 kilometers, with an orbital period of 1 day, 11 hours, and 53 minutes. In 2012, a second satellite orbiting at a distance of 378 kilometers with a diameter of 1.2 kilometers was discovered, with a rotation period of 214 days. The discovery was announced in late 2013. This made 2577 Litva the 11th asteroid discovered to be in a trinary system.Additional observations in 2014 gave a refined period of 7000281218600000000♠2.812186±0.000005 hours, using a statistical Bayesian inference methodology.The minor planet was named after the Russian name for the Baltic state Lithuania, former member of the Soviet Union and now an independent Republic."@en }
