When you say common center of mass, so you mean the as in something like… Once it is outside of the object? Otherwise I assume everything has a common center of mass with everything.
Common center of mass means they spin around each other, having an equal gravitational pull against each other.
Currently the moon orbits earth, but long long in the future, even though the moon is smaller, it will have waned the pull of the earth to an extent where you both go around in the same circle, this happens quicker with objects the more equal in size they are
the space inside the circle they form is a point called the common center of mass because it’s where everything else around them will treat their gravity-source to come from, and both objects revolve around this center.

Thanks for the info!
