Pluto's Moons Don't Orbit It.

None of Pluto's five moons actually orbit the dwarf planet, but instead orbit a point outside of Pluto due to the gravitational influence of Charon, its largest moon. The barycenter of the system is actually 960 kilometers from the surface of Pluto, and the four smaller moons have almost perfect patterns in their orbits around the barycenter. This complex dance is a successful cosmic ballet.
