    The dwarf planet Pluto is never out of the news. It is an object of study because it formed and evolved in the outer part of the solar system called the Kuiper Belt. In support of the NASA New Horizons mission, launched in 2006 and on its way to Pluto, Hubble Space Telescope observations are probing the system so the spacecraft can navigate through it. Although the first moon of Pluto, Charon, was discovered in 1978, 3 more moons were discovered between 2004 and 2011 using Hubble. Now a fifth moon has been discovered, suggesting that the Pluto system may have quite a lot of small (and potentially hazardous) bodies in it.
