    The moon is a decent fraction if the Earth’s mass. It has been a while since I calculated it but I recall the “shared gravitation centre” is actually outside the Earth.

      Doesn’t that also technically mean that the earth’s movement technically wobbles fully inside and fully outside it’s orbital line?
