2577 Litva, provisional designation 1975 EE3, is a Hungarian-type Mars-crosser and rare trinary [lower-alpha 2] 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. [lower-alpha 1] 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] [lower-alpha 2]
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]

The asteroid was named after Canadian astronomer David H. Levy.
(185851) 2000 DP107 is a sub-kilometer sized asteroid, classified as potentially hazardous asteroid and near-Earth object of the Apollo group that is notable because it provided evidence for binary asteroids in the near-Earth population. The PROCYON probe developed by JAXA and the University of Tokyo was intended to flyby this asteroid before its ion thruster failed and could not be restarted.
1717 Arlon, provisional designation 1954 AC, is a binary Florian asteroid from the inner regions of the asteroid belt, approximately 8.5 kilometers in diameter.

Discovered by Yrjö Väisälä at the Turku Observatory in 1938, the asteroid was later named after the Nordic country of Finland. The system's minor-planet moon was discovered in 2007. It has a derived diameter of 1.95 kilometers and is orbiting its primary every 23.55 hours.
5143 Heracles, provisional designation 1991 VL, is a highly eccentric, rare-type asteroid and synchronous binary system, classified as near-Earth object of the Apollo group, approximately 4.8 kilometers in diameter. The asteroid was discovered on 7 November 1991, by American astronomer Carolyn Shoemaker at Palomar Observatory in California, United States. It is named for the Greek divine hero Heracles. It has an Earth minimum orbit intersection distance of 0.058 AU (8.7 million km) and is associated with the Beta Taurids daytime meteor shower.
