[1][6] Based on a short 7-day observation arc from that apparation, it was listed for 12 years on the Sentry Risk Table as the asteroid with the greatest known probability (5%) of impacting Earth.
As of the December 2022 solution which accounts for nongravitational forces,[3] there is a 1-in-10 chance of an Earth impact on 5 September 2095.
[4] NASA's Near Earth Program estimates its size to be 7 meters (23 feet) in diameter with a mass of around 500 tonnes.
[3][9] An asteroid roughly 7-meters in diameter impacting Earth would cause very little danger of harm, but a rather impressive fireball is expected (estimated in the risk table as nearly 9 KT of energy release[4]) as the rock airbursts in the upper atmosphere.
[10] The power of the airburst would be somewhere between the 2–4 m Sutter's Mill meteorite and the 17 m Chelyabinsk meteor (which had 440 KT equivalent energy).
