Kepler's second law, which states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time, is a consequence of the conservation of angular momentum. This law implies that a planet moves faster when it is closer to the Sun and slower when it is farther from the Sun, maintaining constant angular momentum.
