    No, this is actually really relevant. This is part of the logic applied to labeling Pluto a dwarf planet. Pluto and it’s moon do this, Earth and our moon do not. Yes, obviously the center of mass of the two isn’t the exact center of the earth but it’s still within the earth.

      And Pluto knows that Pluto’s
      Hot shit
      And you know Pluto knows it
      “I won’t ever be a planet
      It don’t matter 'cause I know that I’m still”
      Hot shit
      “And you’re hot shit too, so get out of your brain And just do what you’re supposed to do”

      Asking a physicist about the center of an object is like asking a Tumblr user about thr color of the sky. The only response will be “which one?” And a sigh of exhaustion

      Center of volume ≠ center of mass ≠ center of systemic gravity ≠ center of lift…

        Not to mention “an object” is just a construct describing a collection of molecules that themselves don’t necessarily sit still or all stick around.

      but the density of an object is variable. i mean you can define the diffrence between an orbit and a co-spiral to be based on the physical size of the denser planetary body containing the orbit center point, though that seems arbitrary.
