Well it looks like Pluto could possibly have two new satellites - we should know for sure early next year when the team that made the discovery can get more telescope time to confirm it. But it looks pretty likely as they have likely discovered the two satellites in images of the area back in 2002 too - in roughly the same positions as they had calculated.

The two objects designated by the Minor Planet Center of the International Astronomical Union as S/2005 P1 and S/2005 P2 will more formally named once it is confirmed they are indeed satellites.
