}}885 Ulrike, provisional designation {{mp|1917 CX}}, is a background asteroid from the outer regions of the asteroid belt, approximately {{convert|33|km|mi|abbr=off|sigfig=2|sp=us}} in diameter. It was discovered on 23 September 1917, by Soviet astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[1]

Naming

This minor planet was allegedly named after Ulrike von Levetzow (1804–1899), a friend and last love of the German poet Johann Wolfgang von Goethe, who met Ulrike during summertime 1821–1823 in Marienbad, Bohemia.[2]

Orbit and classification

When applying the hierarchical clustering method to its proper orbital elements, Ulrike is a non-family asteroid of the main belt's background population (Nesvorny) and a core member of the Themis family (Zappalà; Milani and Knežević), respectively.[5][6]

It orbits the Sun in the outer main-belt at a distance of 2.5–3.7 AU once every 5 years and 5 months (1,986 days; semi-major axis of 3.09 AU). Its orbit has an eccentricity of 0.19 and an inclination of 3° with respect to the ecliptic.
