    Blixen is a member of the Eos family (606), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids. It orbits the Sun at a distance of 2.9–3.2 AU once every 5 years and 3 months (1,905 days). Its orbit has an eccentricity of 0.05 and an inclination of 12° with respect to the ecliptic.[1]

    Photometric observations of this asteroid collected during 2006 show a rotation period of 6.456 ± 0.003 hours with a brightness variation of 0.20 ± 0.02 magnitude.[6]

    This minor planet was named after Danish novelist Karen Blixen (1885–1962), best known for the memoir Out of Africa.[2] The approved naming citation was published by the Minor Planet Center on 18 September 1986 (M.P.C. 11161).[7]
