What Hubble can tell us

This is an artist's rendering of the Pluto system as seen from one of its moons. The satellites all appear to rotate counterclockwise around Pluto. Pluto is at the center right while Charon is to the right of Pluto. NASA believes that Pluto has a rocky surface likely covered in frost and ice with temperatures around minus 375 to 400 degrees. Pluto does not orbit the sun the same way the planets do. Instead, Pluto orbits on a tilted ellipse. Because of this, it is sometimes closer to the sun than Neptune.
