2014 MV67

2014 MV67 (also written 2014 MV67) is a lost asteroid with an observation arc less than 1 day. It has an assumed orbital eccentricity[lower-alpha 1] and a very poorly constrained orbit.[1] Depending on the orbit, it could be a potentially hazardous asteroid roughly 540 meters (1,770 feet) in diameter. It was discovered on 24 June 2014, when the asteroid was estimated to be 0.97±0.75 AU from Earth and had a solar elongation of 161 degrees.

    The 22 March 2018 and 3 April 2019 virtual impactors did not occur.[3] 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 7 AU from the Sun (beyond the orbit of Jupiter).[lower-alpha 2] The asteroid was not expected to be near Earth anytime during 2019.[4]

    With an almost meaningless 1-day observation arc, the Sentry Risk Table shows an estimated 1 in 3 billion chance of the asteroid impacting Earth on 22 March 2022.[3] The nominal JPL Horizons 22 March 2022 Earth distance is 3.5 AU (520,000,000 km; 330,000,000 mi) with a 3-sigma uncertainty of ±16 billion km. NEODyS lists the nominal 22 March 2022 Earth distance as 2.2 AU (330,000,000 km; 200,000,000 mi).

    Notes
    1. The Minor Planet Center's uncertainty code (orbit note) "E" stands for "Eccentricity assumed", as per Publishable Notes for Orbits of Minor Planets
    2. Jupiter is 5 AU (750 million km) from the Sun. The asteroid's aphelion range (furthest distance from the Sun) is estimated to be 3.1±4.2 AU.
