New "moons" for Pluto? Early news

The leading theory for the formation of Charon involves a large object striking Pluto. The debris from that collision could have formed the two smaller moons, Weaver speculates. It can't be ruled out that they might have been captured into the System, but that seems very unlikely, he said. The two new moons are between 30/40 and 100/125 miles (48/64 to 160/200 Km) in diameter. There is not enough data to pin their size down exactly, however. The moons were found using the HST.

The moons are catalogued as S/2005 P1 and S/2005 P2 for now.
Once they are confirmed, the discoverers will suggest names, to be approved by the IAU (International Astronomical Union).
