new moon orbits Pluto
Re: new moon orbits Pluto
What bugged me about Pluto was that it became pretty clear that it was part of the Kuiper Belt, which going by historical precedent implies "not a planet". Orbital inclination was weird but didn't particularly bug me. These days of course we have the Upsilon Andromedae system with a mutual inclination of 30 degrees between the second and third gas giants, which kind of throws the inclination argument for planethood well out of the window...

Re: new moon orbits Pluto
Don't get me wrong. I laugh at the humor I find in it. I'm ok with calling it a dwarf planet. I think it will be really neat to see what New Horizons reveals about Pluto and its moons.

PS-like the work on the models!

Re: new moon orbits Pluto
This will be neat when New Horizons gets there...instead of 2 Kuiper Belt objects, we get to see 6. Not a full sampling of what such objects look like, but it's something.

Re: new moon orbits Pluto
I'll try but some days ago I try to add Pluto moons based on plu022.bsp but it's does't work
With plu021.bsp it's work fine.
With plu021.bsp it's work fine.

Re: new moon orbits Pluto
When I replace P4 with your code , Nix, Hydra and P4 are gone. I have only Pluto, Charon and P5

the history IN the kernel dose state it used a "p5.bsp" that is nowhere to be found in the PUBLIC files ( at least i can not find it)
jpl horizons only lists
pluto
Charon - 901

but no 905 s/2012
well an updated pluto SPICE ssc

Sorry but it's not working
I've got only Pluto, Charon and P5. P4, Nix and Hydra are missing.
I try to add second your ssc file and replace my ssc with your code deleting Replace text in code.

How did you know what EllipticalOrbit data are Before and After Spice data ?
