Well if the sun is helium and hydrogen gas (if you believe the "scientists" or attended elementary school you would know this), the buoyancy of the gasses put it quite high in the Atmos. The moon is plasma in my opinion and it is at the same height as the sun imo. There is a reason we don't see "the dark side of the moon". It's because it doesn't exist imo. Moon is a plasma reflection of the Earth's surface imo.
