Nix a Moon of Pluto

I was discovered by the Pluto Search Team in 2005 My large red impact crater showing them I am semi-alive. I have since discovered it was June fifteenth by earth years My image got uploaded by New Horizons, one of my fears They named me Nix, after a Greek Goddess of the Night. I have no qualms about this, shall stir up no argument or fight. I am one of five moons, smack in the middle, orbiting Pluto. Charon, Styx, Kerberos and Hydra are the others I know. Some say I am thirty miles across, others say it is forty. I am elongated, for a moon, I am certainly no shorty. I was surprised to see Earthlings had advanced this far. I did not think at this time they would reach even one star.
