A team of astronomers in the US has confirmed the existence of two new
moons orbiting around Pluto. The moons, dubbed rather prosaically P1 and
P2, were initially detected by the Hubble Space Telescope last year and
are the first objects to be discovered around the planet since its first
moon, Charon, was found nearly 30 years ago. The moons are estimated to
have diameters of between about 48 and 165 kilometres and are therefore
much smaller than Charon, which is around 1200 km across. The discovery
also makes Pluto the first Kuiper-belt object to have more than one
satellite (Nature 439 943).

Bet that mess out there is unstable, hope they leave a camera to watch it
fly apart.
