What would be the most significant change in the plot if the planet were more massive?
A) It would not change, because it describes the motion of the star, not the planet.
B) The peaks and valleys would get larger (greater positive and negative velocities) because of larger gravitational tugs.
C) The peaks and valleys would get closer together (shorter period) because of larger gravitational tugs.
B) The peaks and valleys would get larger (greater positive and negative velocities) because of larger gravitational tugs.
