On January 1 2019, New Horizons will fly by its target, nicknamed Ultima Thule, approximately four billion miles from Earth - the farthest space probe flyby in history. This encounter complements the discoveries still coming from the mission's July 2015 exploration of the Pluto system. However, this time, the spacecraft will come three times closer to Ultima than it did to Pluto.
