It was first observed on 5 April 2010, by astronomers of the Catalina Sky Survey at Mount Lemmon Observatory, Arizona, United States, four days before a close approach to Earth at 1.1 lunar distances on 9 April 2010. It has not been observed since. Orbit and classification 2010 GA 6 is an Apollo asteroid. Apollo's cross the orbit of Earth and are the largest group of near-Earth objects with nearly 10 thousand known members. It orbits the Sun in the inner main-belt at a distance of 0.93–3.68 AU once every 3 years and 6 months (1,279 days; semi-major axis of 2.31 AU). Its orbit has a high eccentricity of 0.60 and an inclination of 10° with respect to the ecliptic. With an aphelion of 3.68 AU, it is also a Mars-crossing asteroid, as it crosses the orbit of the Red Planet at 1.666 AU. Close approach With a 1-day observation arc, 2010 GA 6 had a 1 in 6 million chance of impacting Earth in 2074. It was removed from the Sentry Risk Table on 8 April 2010. The asteroid has now a minimum orbital intersection distance with Earth of 0.00607 AU km mi on off 3 flip, which corresponds to 2.4 lunar distances, and is notably larger than the nominal distance of its 2010-flyby. 2010 flyby On 9 April 2010, 02:07 UT, the asteroid passed Earth at a nominal distance of 0.0029 AU km mi on off 3 flip or 1.1 lunar distances. A stony asteroid 22 meters in diameter can be expected to create an air burst with the equivalent of 300 kilotons of TNT at an altitude of 21 km ft us. Generally only asteroids larger than 35 meters across pose a threat to a town or city. There are no projection of future close approaches to Earth available. Physical characteristics According to NASA astronomers, 2010 GA 6 measures approximately 22 m ft us in diameter. Based on a generic magnitude-to-diameter conversion, the asteroid measures between 19 and 36 meters in diameter, for an absolute magnitude of 22.6, and an assumed albedo between 0.057 and 0.20, which represent typical values for carbonaceous and stony asteroids, respectively.
