2012 TC4 is a tumbling micro-asteroid classified as a bright near-Earth object of the Apollo group, approximately 10 meters (30 feet) in diameter.[6][7][8] It was first observed by Pan-STARRS at Haleakala Observatory on the Hawaiian island of Maui, in the United States. As of 1 October 2017, it had a small Earth minimum orbital intersection distance of 0.000149 AU (22,300 km).[2] On 12 October 2017, it passed Earth at 0.00033524 AU (50,151 km).[2] The asteroid was removed from the Sentry Risk Table on 16 October 2017[11] and with a 5-year observation arc has a well-known orbit.[2] For example, on the previously risk-listed date of 12 October 2022,[12] it is now known that the asteroid will be more than 3 AU (450 million km) from Earth.[13]
