The Sun forms a counterbalance to all of the planets , so it is near the barycenter when Jupiter is on one side and the other three jovian planets are diametrically opposite on the other side , but the Sun moves to 2.17 solar radii away from the barycenter when all jovian planets are in line on other side .
