Pluto is a long way away, and so far these are the best pictures of this distant object. That will change in July 2015, when the New Horizons space-probe finally arrives at Pluto. Pluto has 5 known moons, the largest is called Charon. New Horizons was launched in 2006.
After touring the Pluto system, New Horizons will fly farther away from the Sun. It will enter the zone of space known as the Kuiper Belt to examine some of the icy mini-worlds in that vast region beyond Pluto's orbit.
