Provisionally named "S/2012 (134340) 1," the new moon was detected in nine separate sets of images taken by Hubble's Wide Field Camera 3 in late June and early July.
The newly discovered moon is estimated to be tiny and irregularly shaped, measuring just six to 15 miles across and following a 58,000-mile-diameter circular orbit around Pluto.
Pluto's largest moon, Charon, was discovered in 1978. Hubble found two more small moons -- Nix and Hydra -- in 2006, followed by the discovery of one more, P4, last year.
Yes, New Horizons will send back some fascinating data regarding the mysterious Pluto system.
Looking forward to it!
