    1977 Shura, provisional designation 1970 QY, is a stony asteroid from the outer region of the asteroid belt, about 16 kilometers in diameter. It was discovered by Russian female astronomer Tamara Smirnova at the Crimean Astrophysical Observatory in Nauchnyj on 30 August 1970.[7]

    In the SMASS taxonomy scheme, the stony S-type asteroid is classified as a transitional Sq- subtype to the elusive Q-type asteroids of the main-belt.[1][8] It orbits the Sun at a distance of 2.6–3.0 AU once every 4 years and 8 months (1,693 days). Its orbit shows an eccentricity of 0.07 and is tilted by 8 degrees to the plane of the ecliptic. It has a rotation period of 7.5 hours[6] and a geometric albedo of 0.19 and 0.13, according to the surveys carried out by the Japanese Akari and NASA's WISE spacecraft, respectively.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) assumes a somewhat higher albedo of 0.20.[3]

    The minor planet was named after Aleksandr Kosmodemyansky (1925–1945), Hero of the Soviet Union, who died at the age of 19 during the Great Patriotic War, shortly after the Battle of Königsberg. "Shura" is a pet name for Aleksandr. The minor planets 1793 Zoya and 2072 Kosmodemyanskaya were named after his sister and mother.[2]
