Dated news about Plutofrom my Cairene backlog

"Two tiny, additional moons have been found around Pluto, making it the first object in the outer solar system known to have multiple satellites. But how the moons got there remains a mystery.

"The moons, designated S/2005 P1 and S/2005 P2, appear to be just 140 kilometres and 125 km wide, respectively, although their exact sizes will remain uncertain until astronomers determine how much sunlight their surfaces reflect. They lie about twice as far from Pluto as Charon does, with the smaller object about 49,000 km from its host planet and the larger moon at a distance of about 65,000 km.

"And based on the new observations, taken in May 2005 – and Hubble images from 2002 that the team recently re-analysed – the moons appear at this stage to orbit Pluto on circular paths, in the same plane as Charon."
