Discovery of two new satellites of Pluto
Article Abstract:
The discovery of two additional moons around Pluto, named P1 and P2, makes Pluto the first Kuiper belt object known to have multiple satellites, the first satellite of Pluto being Charon. They are much smaller than Charon, with P1's diameter estimated to be ranging from 60 to 165 km, and P2 is 20% smaller than P1, and they appear to be moving in circular orbits in the same orbital plane as Charon.
