The diagram below represents a planet revolving in an elliptical orbit around a star. As the planet makes one complete revolution around the star, starting at the position shown, the gravitational attraction between the star and the planet will

• decrease, then increase

• increase, then decrease

• continually decrease

• Remain the same
