    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.
