Charon, Pluto’s largest moon, has a tidally locked orbit. This means that if our crew can see Charon from where they landed, it will never move across the sky. Charon is also much closer to ...

This event probably scattered these tiny worlds into orbit around Pluto and Charon. To give you an idea of scale, Pluto is roughly 66% the diameter of the Moon, and is only 18% of its mass.
