1977 Shura, provisional designation 1970 QY, is a stony asteroid from the middle region of the asteroid belt, approximately 16 kilometers in diameter. It was discovered on 30 August 1970, by Russian astronomer Tamara Smirnova at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula.[10] The asteroid was named for Soviet Aleksandr Kosmodemyansky.[2]

Orbit and classification

Shura orbits the Sun in the central main-belt at a distance of 2.6–3.0 AU once every 4 years and 8 months (1,694 days). Its orbit has an eccentricity of 0.07 and an inclination of 8° with respect to the ecliptic.[1]

The asteroid was first observed as 1942 RW at

Turku Observatory in 1942. The first used observation was a precovery taken at Goethe Link Observatory in 1954, extending the body's observation arc by 16 years prior to its official discovery observation at Nauchnyj.[10]

A rotational

U=3).[7]

Diameter and albedo

According to the space-based surveys carried out by the Japanese

albedo of 0.19 and 0.13.[4][6] The Collaborative Asteroid Lightcurve Link (CALL) assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 14.9 kilometers.[3]

Between 2005 and 2022, 1977 Shura has been observed to occult three stars.

Spectral type

CALL characterizes Shura as a stony

Q-type asteroids of the main-belt.[1][8] Shura is also characterized as a carbonaceous C-type asteroid by Pan-STARRS' photometric survey.[9]
