1369 Ostanina, provisional designation 1935 QB, is a carbonaceous asteroid from the outer region of the asteroid belt, about 41 kilometers in diameter. It was discovered 27 August 1935, by Soviet–Russian female astronomer Pelageya Shajn at Simeiz Observatory, located on the Crimean peninsula.[10]
The C-type asteroid orbits the Sun at a distance of 2.5–3.8 AU once every 5 years and 6 months (2,019 days). Its orbit shows a notable eccentricity of 0.21 and is tilted by 14 degrees to the plane of the ecliptic. It has a rotation period of 8.4 hours.[7][9] According to the space-based surveys carried out by IRAS, Akari, and WISE, it has a low albedo between 0.05 and 0.06, typical for a carbonaceous C-type asteroid.[4][5][6]
The minor planet was named after the small village Ostanina, located in Perm Krai, now part of the Russian Volga district.[2]
