re: was this correct?
The orbit is not well defined- I dont know all the details, so I cant offer a lot ...the estimate of the period is based solely on the previous estimate of Xena's mass, or on 'hints' of the moons existance from previous observations-'Xena' was previously estimated to be 1.5 times the mass of Pluto.
I do know that definative numbers on the orbit of the moon will require further observation...
