Anyway, Pluto is phase-locked with its moon, Charon. Pluto's own rotation is also phase-locked to its moon, meaning that not only does one side of Charon always face Pluto, but Pluto's rotation matches the orbital period of Charon, so that one side of Pluto is always facing Charon. Eventually, the earth's rotation will match the orbital period of our moon too, so that the same side of earth will always face the moon, and the other half of the planet will just be out of luck. ;)
Thanks for the belief change. Quite interesting.
