NASA has selected the potential next destination for the New Horizons mission to visit after its historic July 14, 2015 flyby of the Pluto system. The destination is a small Kuiper Belt Object (KBO) known as 2014 MU69 that orbits nearly a billion miles beyond Pluto. Scientists estimate that PT1 is just under 30 miles (about 45 kilometers) across. Early target selection was important, as the team needs to direct New Horizons toward the object this year in order to perform any extended mission with healthy fuel margins.
