NASA’s New Horizons probe has already made history several times. At launch, it was the fastest probe ever launched from Earth with a speed of more than 36,000 mph. It was also the first spacecraft to study the dwarf planet Pluto up close. Now, it’s on track for another first. In late 2018, New Horizons will encounter a Kuiper Belt object known as MU69. It turns out this object could be two or even three distinct bodies.
