Name Pluto’s Moons

Pluto system (NASA)


The erstwhile planet Pluto has some company. Its largest moon Charon, which is almost half as wide as Pluto itself, was discovered in 1978. Two smaller moons, now called Hydra and Nix, were discovered in 2005. Then, in 2011 and 2012, images from the Hubble Space Telescope revealed two more moons, which are currently just known as P4 and P5. A list of possible names for the two satellites has been drawn up, and you can vote on your choices here–or, you can suggest names of your own.
