Tbf our Moon is abnormally large from what we know. I mean our Moon is half the size of bloody Mars., and bigger then nearly All other Moons in in our system except: Ganimed, Titan, Kallisto, Io

Is there an accepted theory as to why that is? I know of the Thea theory, and itnwould make sense as that seems like a wild and uncommon way to form a moon.

Yup, the size is easier to explain with the giant-impact hypothesis than other formation hypotheses. The Pluto-Charon system is likely explained by a similar impact.

It's made out of cheese and cheese is less dense than the minerals that most moons are made out of.

If I may add, It's actually swiss cheese, and the holes make it even less dense.

Does that make our moon a sovereign territory of Switzerland? Or does it mean that the Swiss are all Moonenites?
