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]
