2577 Litva, provisional designation 1975 EE3, is a Hungarian-type Mars-crosser and rare trinary [b] asteroid from the inner regions of the asteroid belt, approximately 4 kilometers in diameter.
It was discovered on 12 March 1975, by Soviet–Ukrainian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula. [3] It was named for the former Lithuanian Soviet Socialist Republic, which is now the nation of Lithuania. [2]
Litva 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 has an eccentricity of 0.14 and an inclination of 23 ° with respect to the ecliptic. [1]
In the Tholen taxonomy, Litva is classified as an EU-type, a subtype of the bright E-type asteroids. [1] It has also been characterized as a Sl-type and Q-type asteroid by astronomers using the New Technology Telescope at La Silla and by PanSTARRS' photometric survey, respectively. [12] [13]
The body has a rotation period between 2.81288 and 2.82 hours, [5] [6] [7] [8] [9] superseding the original measurement that gave 5.618 hours. [10] Most recent photometric observation from 2014, gave a refined period of 2.812186 hours, using a statistical Bayesian inference methodology. [15]
In March 2009 the Central Bureau for Astronomical Telegrams announced the discovery of a moon orbiting the asteroid. [a] 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 orbitial 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. [16] [b]
This minor planet was named after the Russian name for the Baltic state Lithuania, former member of the Soviet Union and now an independent Republic. [2] The official naming citation was published by the Minor Planet Center on 1 December 1982 ( M.P.C. 7472). [17]
