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.

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.

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