The moon travels around earth slower than the earth turns. Charon is orbiting around Pluto at almost the same speed as Pluto's rotation, as if it were attached to Pluto at a fixed point by a long rod. If Charon were further from Pluto but still traveled at the same speed that it does now (i.e. a larger orbital path), it would "move" across Pluto's sky like the moon does in ours.

the placement of the centre of mass of the two physique device. Pluto and Charon are somewhat comparable in length, and the centre of mass of that device is someplace between them, in empty area. The Earth-Moon 2 physique device has the centre of mass someplace in the gap occupied via Earth, because of the fact the Earth is heavily greater beneficial than the moon.

The principle is the same that they use for geostatic satellites.
If you place the satellite (moon) at the right distance and traveling at the same speed of the rotation of the object it orbits, it will stay in place (apparently). But this is only apparent, because in reality it is falling in an orbit, but it cannot be perceived because the planet is also rotating.
