}}{{mp|2014 MV|67}} (also written 2014 MV67) is a Mars-crosser and former lost asteroid with an observation arc of less than 1 day. Before its recovery, it had an assumed orbital eccentricity{{efn|name=assumed}} and a very poorly constrained orbit. Depending on the orbit, it could have been a potentially hazardous asteroid, roughly {{convert|540|m|ft|sigfig=3|abbr=off|sp=us}} in diameter, or it could turn out to be a Mars-crosser or even a main-belt asteroid as were the cases with {{mpl|2004 BX|159}} and {{mpl|2010 GZ|60}}.{{efn|name=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.{{efn|name=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 {{convert|1.1|+/-|0.84|AU|e6km|abbr=unit|lk=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 {{Nowrap|±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.{{efn|name=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.{{efn|name=background2022}} The nominal JPL Horizons 22 March 2022 Earth distance is {{convert|2.2|AU|km mi|abbr=on}} with a 3-sigma uncertainty of {{Nowrap|±3 billion km}}. NEODyS also lists the nominal 22 March 2022 Earth distance as {{convert|2.2|AU|km mi|abbr=on}}. And again it is not expected to be near Earth anytime during 2022.

Notes

{{notelist|refs=

{{efn|name=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.}}

{{efn|name=assumed|The Minor Planet Center's uncertainty code (orbit note) "E" stands for "Eccentricity assumed", as per [https://www.minorplanetcenter.net/iau/info/OrbNote.html Publishable Notes for Orbits of Minor Planets]}}

{{efn|name=aphelion|Jupiter is {{Convert|5|AU|e6km|sigfig=2|abbr=unit|lk=on}} from the Sun. The asteroid's aphelion range (furthest distance from the Sun) is estimated to be {{Val|2.1|0.5|u=AU}}.}}

{{efn|name=background2022|Palermo Scale for 2022 is −4.94 and 10^4.94 {{=}} 87096.}}

{{efn|name=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).}}
