Hubble finds fifth moon orbiting Pluto

"The Hubble Space Telescope has found yet
another moon orbiting what used to be the
last planet in the Solar System.

The moon, the fifth that's been spotted orbiting
Pluto, is an irregularly shaped lump around 6
to 15 miles across and orbits in a plane 58,000
miles around the dwarf planet. It was spotted
in nine images taken with the Hubble's Wide
Field Camera in June and July."
