A planet orbits a star in the path shown in the figure. The planet's mass is much smaller than the star's mass. Which two of the following claims are correct about the accelerations associated with the planet, star, and planet-star system? Select two answers. Justify your selections. A .Both the planet and the star accelerate, because each object exerts a force on the other object. B. Only the planet accelerates, because a force is exerted on the planet but not on the star. C. The center of mass of the planet-star system accelerates, because the planet and star exert forces on each other. D. The center of mass of the planet-star system does not accelerate, because there is no net force exerted on the system.
