  The barycenter of the Earth-Moon system sits well within Earth’s radius. There is no/definition under which the Earth-Moon system is considered binary

    The barycentre of Sun-Jupiter system is outside of the Sun half the time. It’s a really bad metric for determining that, as it depends on the distance between two bodies and not just on their relative masses.

      Except Jupiter is very clearly not a star. It’s an order of magnitude off of the mass required for fusion.

        Who said anything about fusion? I thought the only thing that matters is the position of the barycentre, as you insisted?
