... The massive star is closer to center of mass, and moves more slowly than the planet, but it does move! Example: ignore planets other than Jupiter. Then Sun and Jupiter orbit their common center of mass every 11.86 years. Jupiter’s orbit has semi-major axis of 7.78 x 108 km, while Sun’s semi-major a ...
