(6265) 1985 TW3 is a binary background asteroid from the asteroid belt, approximately 5 kilometers (3.1 miles) in diameter. It was discovered on 11 October 1985, by T. F. Fric and Richard J. Gilbrech at the Palomar Observatory in San Diego County, California.[1] In July 2007, a 1-kilometer sized moon was discovered in its orbit and announced the following month. The moon is separated by 8 km and orbiting once every 15 hours and 52 minutes.[2]
