1369 Ostanina, provisional designation 1935 QB, is a carbonaceous asteroid from the outer region of the asteroid belt, approximately 41 kilometers in diameter. It was discovered on 27 August 1935, by Soviet–Russian astronomer Pelageya Shajn at Simeiz Observatory on the Crimean peninsula.
The C-type orbits the Sun at a distance of 2.5–3.8 AU once every 5 years and 6 months (2,011 days). Its orbit has an eccentricity of 0.21 and an inclination of 14° with respect to the ecliptic. In 1928, Ostanina was first identified as 1928 FE at Heidelberg Observatory, extending the body's observation arc by 7 years prior to its official discovery at Simeiz.
Several photometric light-curve observations gave a rotation period of nearly 8.40 hours with a brightness variation between 0.80 and 1.11 magnitude, indicative of a non-spheroidal shape (U=3/3-/2+/2+).
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Ostanina measures between 40.59 and 43.56 kilometers in diameter and its surface has an albedo between 0.049 and 0.061. The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0545 and diameter of 41.24 kilometers using an absolute magnitude of 10.7.
The minor planet was named after the small village of Ostanina, located in Perm Krai, now part of the Russian Volga district. Naming citation was published before November 1977 (M.P.C. 838; LDS).
