Discovery 2014 MT 69 was discovered by the New Horizons KBO Search with the help of the Hubble Space Telescope (HST)J. R. Spencer M. W.

Preliminary observations by the HST searching for KBO flyby targets for the New Horizons probe started in June 2014, and more intensive observations continued in July and August.Hubble to Proceed with Full Search for New Horizons Targets HubbleSite news release Space Telescope Science Institute July 1, 2014 http://hubblesite.org/newscenter/archive/releases/2014/35/ http://spacefellowship.com/news/art39548/hubble-to-proceed-with-full-search-for-new-horizons-targets.html Hubble to Proceed with Full Search for New Horizons Targets Klaus Schmidt International Space Fellowship 2 July 2014 2014 MT 69 was first discovered in observations on June 24, 2014, during the preliminary observations, but it was designated 0720090F at the time,Hubble Survey Finds Two Kuiper Belt Objects to Support New Horizons Mission http://hubblesite.org/newscenter/archive/releases/2014/35/image/a/ HubbleSite news release Space Telescope Science Institute July 1, 2014 nicknamed "7" for short. Its existence as a potential target of the New Horizons probe was revealed by NASA in October 2014, but the official name 2014 MT 69 was not assigned by the Minor Planet Center (MPC) until March 2015 after better orbit information was available. The parameters of the orbit have the extremely large uncertainty of 9 because follow-up observations after discovery eliminated 2014 MT 69 as a potential target of the New Horizons probe, and no further follow-up observations were made. Potential targets of the New Horizons mission After having completed its flyby of Pluto, the New Horizons space probe was maneuvered for a flyby of at least one Kuiper belt object (KBO). Several targets were considered for the first such flyby. Potential target 2014 MT 69 has a diameter between 20 - 92 km on, which is smaller than the other potential targets of the New Horizons probe. A potential encounter initially looked more feasible for 2014 MT 69 than for 486958 Arrokoth, but follow-up observations eventually ruled out 2014 MT 69 as a potential target. The potential targets for the New Horizons probe were PT1 and PT3, the KBOs Arrokoth and 2014 PN 70, and the probe had sufficient fuel to maneuver to either PT1 or PT3. Potential target PT2, the KBO 2014 OS 393, was eliminated for consideration as a potential target.Powell, Corey S.
