A planet and moon are circling a star. The moon, for whatever reason, starts to pick up mass. This process continues to the point that the planet and moon are of equal mass. At this point, would the planet and moon start circling each other? <br /><br />The moon continues to increase in mass and now is larger than the planet. Would the moon cease circling the planet and would the planet now circle the moon? <br /><br />I realize this scenario would probably cause a collision and we would end up with a large planet, but I would like to put this possibility to the side<br />
