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

I believe that’s the same for every planet. And every moon. For every orbit.
Its just that the barycenter is inside the more massive object when one is much more massive than the other. Not that this makes much of a difference to anything.

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

I just can’t remember their names :-(

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 ;)

Is that a problem?

depends! do you wanna know how the system will evolve over long periods of time?
… then yes!

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

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

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

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

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.
