For a dwarf planet, Pluto has a lot going on around it.
Scientists announced today the discovery of a fifth moon around Pluto, which was once considered the ninth planet in our solar system. The moon was spotted by researchers using NASA's Hubble Space Telescope. The new moon joins P4, which was found last year, and Nix and Hydra, which were discovered in 2005. According to Space.com, the dwarf planet's other known moon, Charon, was discovered in 1978.
