    Is our moon really that big? I thought Charon-Pluto is kinda a special cases that they look like twin planets instead

      I think part of it is that Mt Everest is a lot smaller than you’d think when you’re looking at this scale. The moon is only 2% of the Earths volume so when you spread it over the Earths surface it’s really like a thin thin film to cover the whole surface. But the truth is that all of human experience is an even thinner film smeared across the surface.

            Yeah, but from surface to space it’s ruthly 100 km, so 43 km is quite the cover. Then again, I get what you are saying. I gues it’s a matter of perspective.

            Ah I see. Although the comic spreads the moon “relatively”, it presents it absolutely. Although interesting in by itself it does feels it’s missing something.
