    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.[1] 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.[3] 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.[5]

    Closest approach to Earth in 2022 occurred on 13 March 2022 at a distance of about 7.7 million km.[2] It will come to perihelion (closest approach to the Sun) on 25 April 2022.
