Clyde Tombaugh discovered Pluto on February 18 1930. Did you know that Pluto has five moons? Their names are Charon, Nix, Kerberos, Styx and Hydra. Pluto was named after the ancient roman god of the underworld all because of an 11 year old girl in England. Since Pluto was the roman god of the underworld, the planet’s main moon, Charon, is named after the ferryman who carries the dead souls across the river Styx into the underworld. A day on Pluto is 6.4 Earth days. Pluto is the biggest dwarf planet.

Once you've given something planetary status it's kind of mean to take it away." - Jared Leto "Pluto, are favourite dwarf planet since 2006" - Google
