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

    The asteroid orbits the Sun at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,341 days). Its orbit shows an eccentricity of 0.21 and an inclination towards the ecliptic of 8 degrees. The S-type body has an albedo of about 0.2[5] and a rotation period of 7.3 hours.[7][8]

    It 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]
