Our moon is only the largest moon to planet ratio in our solar system if you discount Pluto as a planet.

Fun fact: if Luna was only about 30% heavier than it is currently, the Earth's barycenter would lie outside of Earth, which would potentially make Earth not count as a planet by the modern IAU definition.

The real question is... Could such a situation be inhabitable, could life evolve on such a world?

There's also an argument that the moon isn't actually a moon since it doesn't actually orbit around the Earth. If you look at their respective orbits, the moon and Earth kind of shift places like a spinning helix pattern and the orbit of the moon is more tied to the sun than the Earth.

I haven't watched this all the way through, but it looks to largely cover the same material. I don't know how common this is among moons, but I think it makes Earth's relationship with its moon that much more special.

Forgetting Pluto and Charon, drag sees.
