Astronomers using NASA's Hubble Space Telescope have confirmed the presence of two new moons around the distant planet Pluto. The moons were first discovered by Hubble in May 2005, but the Pluto Companion Search team probed even deeper into the Pluto system with Hubble on Feb. 15 to look for additional satellites and to characterize the orbits of the moons. In the image, Pluto is in the center and Charon is just below it. The moons, provisionally designated S/2005 P 1 and S/2005 P 2, are located to the right of Pluto and Charon.

The new names designated by the IAU are Nix (134340 II) and Hydra (134340 III).

For quick reference:

S/2005 P 2 = Nix = 134340 II
