@Arkshol93 Neptune going from this to this was a crime against my heart and I can’t forgive it
@lolidk4200 Every planet orbits a larger object, it is called being in the SOLAR (sun) system
@jfbg_200 @TiagoNugent A very good point. Pretty much everyone calls Pandora a planet, even though it is a natural satellite, making it a Moon, so I think that supports my case that moons can be planets and vise versa
@kez611_ the moon is currently classified as a "planetary mass object"
The only reason it isnt currently a planet is because we use the IAU definition instead of the geophysical definition.
I reject the IAU definition, and only use the Geophysical definition
