1709 Ukraina, provisional designation 1925 QA, is a stony asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 16 August 1925, by Soviet astronomer Grigory Shajn at Simeiz Observatory on the Crimean peninsula.[10] It was named in honor of Ukraine .[2]

Orbit and classification

Ukraina orbits the Sun in the inner main-belt at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,340 days). Its orbit has an eccentricity of 0.21 and an inclination of 8° with respect to the ecliptic.[1]

The body's observation arc begins at Heidelberg, five days after its official discovery observation at Simeiz.[10]

Physical characteristics

The S-type asteroid has an albedo of about 0.2[4] and a rotation period of 7.3 hours.[7][8]

Naming

This minor planet was named after the country Ukraine , then the Ukrainian Soviet Socialist Republic (1922–1991). The name was proposed by the Institute of Theoretical Astronomy in Leningrad, what is now St. Petersburg.[2] The official naming citation was published by the Minor Planet Center on 1 June 1967 (M.P.C. 2740).[11]
