Uranus rules surprising events, so it’s an interesting synchronicity that a new Moon around Pluto is discovered just as the square between Uranus and Pluto reaches its closest point until next year. Temporarily named P-4, the new moon may ultimately be called Cerberus after the dog that guards the gates of Hades.

The New Horizons mission is expected to reach Pluto in 2015, just as the square of Uranus to Pluto reaches its completion.
