2001 GO2 is a very small asteroid and near-Earth object of the Apollo group, approximately 50 meters (160 feet) in diameter. Like 2003 YN107, it is in a co-orbital configuration relative to Earth moving in a 1:1 mean-motion resonance. It was first observed on 13 April 2001, by astronomers with the LINEAR program at the Lincoln Lab's ETS near Socorro, New Mexico, in the United States.[1] 2001 GO2 has not been observed since its short four-day observation period in April 2001.
