In the figure below, Planet X is moving in a perfectly circular orbit around its companion star. The time between each position shown is exactly one month: 1. Write down Kepler’s second Law of planetary motion. 2. Does the planet obey Kepler’s second law? How do you know? 3. If you carefully watched this planet during the entire orbit, would its speed be increasing, decreasing, or staying the same? How do you know?
