900 Rosalinde (prov. designation: A918 PJ or 1918 EC) is an elongated background asteroid from the inner regions of the asteroid belt, that has a mean diameter of approximately 19 kilometers (12 miles). It was discovered on 10 August 1918, by astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The lengthy S/D-type asteroid has a rotation period of 16.6 hours. It was likely named after "Rosalinde", a character in the operetta Die Fledermaus by Johann Strauss II.[2]
