Two Hubble Space Telescope images showing Pluto and its moons Charon, Nix, Hydra, and the newly discovered moon P4. The images, taken on June 28 and July 3, 2011, reveal the faintest and smallest moon of Pluto, P4, which orbits Pluto in about 31 days. Image artifacts are visible due to long exposures.
