317 Roxane is anasteroid from theasteroid belt approximately 19 km indiameter. It was discovered byAuguste Charlois fromNice on 11 September 1891. The name was chosen by F. Bidschof, an assistant at theVienna Observatory, at Charlois' request; Bidschof chose to name it afterRoxana, the wife ofAlexander the Great, and at first used the spelling "Roxana".[3][4][5]
In 2008, a team identified Roxane as the closest knownspectroscopic match for the Peña Blanca Springmeteorite that landed in a swimming pool inTexas in 1946. There is a possibility, therefore, that 317 Roxane is from the same parent object as this meteorite.[6]
In 2009, a team using theGemini Northadaptive optics telescope discovered amoon orbiting Roxane. The moon is namedOlympias, after the mother ofAlexander the Great who was the king ofMacedonia and husband of Roxana. Prior to its naming, the moon was provisionally namedS/2009 (317) 1.[7] It measures 5 km in diameter and orbits 245 km from Roxane, completing one orbit every 13 days.[8]
