"Or isn't the Earth a body that orbits the Moon? Just like two masses of whatever size have equal gravitational attraction, so two bodies in close proximity equally orbit each other." --- smartermind

They're rotating around their 'barycentre' or mutual centre of mass. However for Earth/Moon that point is below the surface of the Earth and for Pluto/Charon that point is well outside Pluto.
