[Data-modeling] Astronomy: Celestial Object modeling on Sandbox (Orbit & Discovery)

[Gordon Mackenzie]

So in the midst of furious testing I cobbled together my exploration of adding discovery information and orbital information to the Celestial Object type (partially robbing the cradle of Exoplanet):

First example is Phobos:

I know it could get quite more detailed with even more properties for the orbital CVT but it may be that there is too much already...We do link to the Wikipedia article that has a quite explicit info box (and we aren't out to replace/fully replicate WP either).

I think I am leaning towards having the specific Mass/Radius/Gravity/Temp information for the more specific object types of Star, Planet, Dwarf Planet, Natural Satellite, Asteroid, and Comet. An example is the size-appropriate use of various Mass and Radius ratios against a particular solar system body; Stars mostly use M(solar), Jovian-sized objects use M(jupiter), and rocky objects often use M(earth).
