They’re tidally locked, showing the same face to each other, with an orbital period of a bit more than six days (it sez here). Charon has a lot lower density which means it wasn’t formed at the same time and place as Pluto. Mike Brown (discoverer / co-discoverer of the larger Kuiper Belt Objects or KBOs) claims that one of those KBOs was formed in a large impact that also gave birth to Pluto and Charon.
