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. 2001 GO₂ has not been observed since its short four-day observation period in April 2001.
