Near-Earth asteroid October 2021 yes #FFC2E0 2009 JF 1 Mount Lemmon Survey 4 May 2009 2009 JF 1 NEO Apollo 2025-Nov-21 (JD 2461000.5) 7 1.2 days 0.000054 AU km on 2.1 AU km on 3.29 AU (Q) 0.4957 AU (q) 2025-Feb-08 ± 3 days 1.89 AU (a) 0.738 (e) 2.6 years 6.15 ° (i) 45.5 ° (Ω) 108 1 ° (M) 281 ° (ω) ~10 m 2 on 8–17 meters 27.73 2009 JF 1 is a small near-Earth object that should have passed within 0.3 AU e6km unit on of Earth in 2022. On 5 February 2022 the 2009 observations were remeasured greatly reducing the odds of an impact. On 6 May 2022 it had a 1-in-140,000 chance of impacting Earth. It is estimated to be 10-meters in diameter which would make it smaller than the Chelyabinsk meteor. It has a very short observation arc of 1.2 days and has not been observed since 2009. On 6 May 2022 it was nominally expected to be 0.2 AU e6km unit from Earth but has an uncertainty region of ±23 e6km AU unit. The nominal Earth approach was 15 May 2022 and would have had the asteroid only brightening to apparent magnitude 26 which would have made it too faint for automated surveys to detect. With a Palermo scale rating of -4.41, the odds of impact were 26000 times less than the background hazard level for an asteroid of this size. +Virtual impactor Date Impactprobability(1 in) JPL Horizonsnominal geocentricdistance (AU) NEODySnominal geocentricdistance (AU) MPCnominal geocentricdistance (AU) Find_Orbnominal geocentricdistance (AU) uncertaintyregion(3-sigma)2022-05-06 140000 0.19 AU e6km unit on 0.16 AU e6km unit 0.19 AU e6km unit 0.19 AU e6km unit ± 23 million km About two months after approaching Earth, it came to perihelion (closest approach to the Sun), but the time of perihelion passage is only known with an accuracy of ±3 days. The asteroid was not recovered due to its small size and distance from Earth.
