1709 Ukraina, provisional designation1925 QA, is a stonyasteroid from the inner regions of theasteroid belt, approximately 9 kilometers in diameter. It was discovered on 16 August 1925, by Soviet astronomerGrigory Shajn atSimeiz Observatory on the Crimean peninsula.[10] It was named in honor ofUkraine.[2]
Ukraina orbits the Sun in theinner main-belt at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,340 days). Its orbit has aneccentricity of 0.21 and aninclination of 8° with respect to theecliptic.[1]
The body'sobservation arc begins atHeidelberg, five days after its official discovery observation at Simeiz.[10]
TheS-type asteroid has analbedo of about 0.2[4] and arotation period of 7.3 hours.[7][8]
Thisminor planet was named after the countryUkraine, then theUkrainian Soviet Socialist Republic (1922–1991). The name was proposed by the Institute of Theoretical Astronomy in Leningrad, what is now St. Petersburg.[2] The officialnaming citation was published by theMinor Planet Center on 1 June 1967 (M.P.C. 2740).[11]
