  Correct.

  I also believe that on of the criteria for a binary planet is that the barycenter is outside either body. Like Pluto/Charon.

    Don’t forget the other 3 bodies in the Pluto/Charon system

      Is that a problem?

      I’ve always preached inclusivity and CC would welcome 3 more planets

        The only one I remember is Styx cause I remember the river from mythology cause I thought it was cool. Not a damn clue what the others were.

        Same. That’s why I was lazy and didn’t even mention them ;)

  I mean, sure, but that’d be like saying I’m pulling the earth towards me when I jump.

    You don’t have to jump, you’re already doing it. Some of us more than others… *Looks in mirror and hangs head

    If you have ever done a handstand then you have lifted over your head the weight that the entire mass of the earth has in your own gravitational field.

    Isn’t that canceled out by the pushing you do when you start to jump?

    • stevedice@sh.itjust.works ⁨1⁩ ⁨day⁩ ago

      Yeah, but then I pull it back as I’m falling.

  Pluto and it’s biggest moon Charon about for the very center outside of each other. This means that you could build a space elevator directly between the surface of each of them and it would rotate around that point since they’re also tightly locked.

  Asteroids everything does to some degree even if miniscule I'd assume.
