A Fourth Moon for Pluto

A fourth satellite has been detected orbiting dwarf planet 134340 Pluto (formerly known as just the planet Pluto) by the Hubble Space Telescope.

The object, bearing a temporary designation of just P4, appears to be a ball of ice roughly 8 to 21 miles across.

Yet another target for the New Horizons spacecraft to photograph when it flies through the Plutonian system in 2015.
