    NASA's New Horizons mission has filed a flight plan for its January 1, 2019, flyby of Kuiper Belt Object (KBO) 2014 MU69, which will bring the spacecraft three times closer to its second target than it came to Pluto during the upcoming encounter.

  • New Horizons’ KBO target may be a binary

    Laurel KornfeldAugust 4th, 2017

    New Horizons' second target – Kuiper Belt Object (KBO) 2014 MU69 – may actually be a binary system composed of two objects that either touch one another or orbit very close together, according to observations conducted by mission scientists when the KBO passed in front of a star on July 17, 2017.

  • New Horizons scientists study KBO by observing star occultation

    Laurel KornfeldJune 23rd, 2017

    A total of 54 New Horizons observation teams successfully obtained crucial data about the spacecraft's second target, 2014 MU69, when the Kuiper Belt Object (KBO) occulted (or passed in front of) a star on the night of June 2–3.

  • Stellar occultations by KBO 2014 MU69 will give scientists crucial data

    Laurel KornfeldMay 28th, 2017

    Members of NASA's New Horizons team will have three opportunities to obtain crucial data regarding 2014 MU69 – the mission's second target – when the Kuiper Belt Object (KBO) occults three different stars within the next few weeks.

  • New Horizons performs course correction on path toward second target

    Laurel KornfeldFebruary 3rd, 2017

    After spending six days in a special mode to capture distant photographs of six Kuiper Belt Objects (KBOs), the New Horizons probe underwent a minor course correction engine burn sending it toward its second flyby target, KBO 2014 MU69.

  • Final Pluto data returned by New Horizons, but analysis is just beginning

  • New Horizons shows possible clouds on Pluto, target KBO reddish

    Laurel KornfeldOctober 20th, 2016

    Data presented by New Horizons mission scientists at the current American Astronomical Society (AAS) Division for Planetary Sciences (DPS) Conference suggest possible clouds in Pluto's hazy atmosphere, and also show the spacecraft's second target, Kuiper Belt Object (KBO) 2014 MU69, to have the same reddish color as Pluto.

  • Dwarf planet with eccentric orbit discovered in the Kuiper Belt

    Laurel KornfeldJuly 13th, 2016

  • KBO selected for New Horizons’ second target

    Laurel KornfeldAugust 31st, 2015

    Only a month and a half after New Horizons' historic Pluto system flyby, the mission team has selected a potential target for the spacecraft's second visit – the tiny Kuiper Belt Object (KBO) 2014 MU69, also known as "PT 1" (Potential Target 1). Orbiting almost a billion miles beyond Pluto, 2014 MU69 is estimated to have a diameter slightly under 30 miles (45 km).
