2022 BX1 is a potentially hazardous asteroid around 200 meters in diameter that was discovered on 25 January 2022 when it was 0.36 AU (54 million km) from Earth. On 29 January 2022 with an observation arc of 22 days it was rated with a Torino scale of 1 for a virtual impactor on 11 July 2061 21:22 UTC. The 2061 virtual impactor was ruled out on 9 February 2022 with a 32.9 day observation arc. Nominal approach is expected to occur 18 June 2061.
