'''1709 Ukraina''', provisional designation {{mp|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.<ref name="MPC-Ukraina" /> It was named in honor of Ukraine.<ref name="springer" />
== 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.<ref name="jpldata" />
The body's observation arc begins at Heidelberg, five days after its official discovery observation at Simeiz.<ref name="MPC-Ukraina" />
== Physical characteristics ==
The S-type asteroid has an albedo of about 0.2<ref name="Masiero-2012" /> and a rotation period of 7.3 hours.<ref name="geneva-obs" /><ref name="Hanus-2011" />
== 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.<ref name="springer" /> The official {{MoMP|1709|naming citation}} was published by the Minor Planet Center on 1 June 1967 ({{small|M.P.C. 2740}}).<ref name="DoMP-Circular-dates" />
