And where does oen get the data for size, orbit, placement, etc of Xena? I mean Charon is roughly the same as pluto since they orbit each other, Cerres is available through AStro.com and other sights, but Xena?
Enquiring minds want to know!

Hi Granny,
"Xena" is not it's official name - that's still to be decided.
It's 2003 UB 313.
I see Achernar's already given you link ... if you want to erect chart with this one, then when you next visit astro.com and extended charts, you'll find a numerical reference (999001) to type in box for asteroids etc at bottom of page.
Best wishes,
TS
