Before its recovery, it had an assumed orbital eccentricityassumed and a very poorly constrained orbit. Depending on the orbit, it could have been a potentially hazardous asteroid, roughly 540 m ft 3 off us in diameter, or it could turn out to be a Mars-crosser or even a main-belt asteroid as were the cases with 2004 BX 159 and 2010 GZ 60.mba It was recovered by Pan-STARRS in September 2021 and is now known to be a Mars-crossing asteroid. Description Main belt asteroids can have perihelia (closest approach to the Sun) as low as 1.7 AU. The 22 March 2022 impact scenario was 87,000 times lower than the background threat generated by unknown asteroids.background2022 It was removed from the Sentry Risk Table on 15 April 2021 when JPL transitioned to planetary ephemeris DE441. It was discovered on 24 June 2014, when the asteroid was estimated to be 1.1 +/- 0.84 AU e6km unit in from Earth and had a solar elongation of 161 degrees. The 22 March 2018 and 3 April 2019 virtual impactors did not occur. The uncertainty region of ±10 billion km wraps around the entire orbit so the asteroid could be anywhere on any of the numerous orbit fits. It could be near aphelion (in the asteroid belt) ~3 AU from the Sun.aphelion The asteroid was not expected to be near Earth anytime during 2019. With an almost meaningless 1-day observation arc, the Sentry Risk Table showed an estimated 1 in 3 billion chance of the asteroid impacting Earth on 22 March 2022, which was 87,000 times lower than the background threat.background2022 The nominal JPL Horizons 22 March 2022 Earth distance is 2.2 AU km mi on with a 3-sigma uncertainty of ±3 billion km. NEODyS also lists the nominal 22 March 2022 Earth distance as 2.2 AU km mi on. And again it is not expected to be near Earth anytime during 2022. +Virtual impactors (past and future) Date Impactprobability(1 in) JPL Horizonsnominal geocentricdistance (AU) NEODySnominal geocentricdistance (AU) MPCnominal geocentricdistance (AU) Find_Orbnominal geocentricdistance (AU) uncertaintyregion(3-sigma)2018-03-22 1.9 billion 2.4 AU e6km unit on 2.5 AU e6km unit 3.8 AU e6km unit 2.3 AU e6km unit ±600 million km2019-04-03 2.1 billion 1.2 AU e6km unit 1.2 AU e6km unit 3.5 AU e6km unit 2.6 AU e6km unit ±600 million km2022-03-22 removed 2.2 AU e6km unit 2.2 AU e6km unit 3.5 AU e6km unitJupiter 2.5 AU e6km unit ±3 billion km2025-03-26 removed 2.8 AU e6km unit 2.8 AU e6km unit 3.4 AU e6km unit 2.4 AU e6km unit ±2 billion km See also 2005 ED 224 2007 FT 3 Notes mba With such short arcs uncertainties can not really be described with formal error bars. In this case non-NEO orbits are definitely possible, perhaps even more likely than NEO ones. assumed The Minor Planet Center's uncertainty code (orbit note) "E" stands for "Eccentricity assumed", as per Publishable Notes for Orbits of Minor Planets aphelion Jupiter is 5 AU e6km 2 unit on from the Sun. The asteroid's aphelion range (furthest distance from the Sun) is estimated to be 2.1 0.5 AU. background2022 Palermo Scale for 2022 is −4.94 and 10^4.94 87096. Jupiter Jupiter is 4 AU from Earth every 13 months when Jupiter comes to opposition (opposite the Sun in the sky with Earth between the two).
