Pluto and Charon (and Styx, Nix, Kerberos, and Hydra!)
Pluto has a lot more in common with the moons of the outer solar system than with the terrestrial planets. We take a brief look at Pluto's discovery and what we learned during the 2015 flyby of the New Horizons mission to Pluto (and beyond!). And get this, Pluto, Charon, Styx, Nix, Kerberos, and Hydra are probably the result of a collision!
