This image shows four photos of Charon, Pluto's moon. The images are centered at 0 degrees of latitude and 0 (top-left), 90 (top-right), 180 (bottom-left), and 270 (bottom-right) degrees longitude. They are based on photometric measurements. Charon's orbit is gravitationally anchored with Pluto, so that both bodies present the same hemisphere to each other constantly.
The surface composition of Charon is different from that of Pluto. The satellite seems to be covered with ice water rather than nitrogen. Density differences indicate that Pluto and Charon were created independently. This rules out the theory of its formation as a double planet.
