Near-Earth asteroid 2022

2022 QX4 is a Tunguska event-sized asteroid, classified as a near-Earth object of the Aten group, approximately 40 meters (130 feet) in diameter.[2] It was discovered by ATLAS on 24 August 2022,[1] when it was 0.03 AU (4.5 million km) from Earth. On 4 September 2022 with an observation arc of 8 days, it was listed with a 1-in-109 chance of impacting Earth with a Torino scale of 1 for a virtual impactor on 4 September 2068 00:52 UTC.[2] Five precovery images from August 2013 were published on 11 September 2022[4] extending the observation arc to 9 years and 2022 QX4 was removed from the Sentry Risk Table. The nominal approach is expected to occur 26 August 2068.[5]
