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




Physical characteristics


The S-type asteroid has an albedo of about 0.2 and a rotation period of 7.3 hours.




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. The official naming citation was published by the Minor Planet Center on 1 June 1967 (M.P.C. 2740).
