885 Ulrike (prov. designation: A917 SV or 1917 CX) is an elongated Themistian asteroid from the outer regions of the asteroid belt. It was discovered on 23 September 1917, by Soviet astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[1] The presumed C-type asteroid has a short rotation period of 4.9 hours and measures approximately 33 kilometers (21 miles) in diameter. It was likely named after Ulrike von Levetzow, last love of Goethe.[2]
