The earth would be a moon of Jupiter not the other way around.
“The earth would be a moon of Jupiter not the other way around.”
Perhaps that is one way of looking at it, but you should realize the Moon/Luna does not orbit around the Earth. The Earth does not orbit around the Moon/Luna. They both orbit around a point in space known as the barycenter, where their gravitational forces equalize. It just so happens the barycenter for the Earth and the Moon/Luna is located near the Earth’s sea level.
