Relative sizes of objects in the Pluto system represented by objects from the Saturn system
The scale of the full-size graphic is 1 kilometer per pixel. The four small moons of Saturn are shown at their correct sizes since the sizes of Pluto's moons are not known sufficiently precisely to warrant any tinkering with the scale. Dione (standing in for Charon) and Rhea (standing in for Pluto) are scaled to 108 and 150 percent of their actual sizes, respectively.
