- Which of the following are, or follow directly from, Kepler's Laws of planetary motion? Check all that apply. More distant planets move at slower speeds. The force of attraction between any two objects decreases with the square of the distance between their centers. The orbit of each planet about the Sun is an ellipse with the Sun at one focus. A planet travels faster when it is nearer to the Sun and slower when it is farther from the Sun. As a planet moves around its orbit, it sweeps out equal areas in equal times.arrow_forwardTwo celestial bodies whose masses are m1 and m2 are revolving around their common center of mass and the distance between them is L.
