Kepler's Second Law, also known as the Law of Equal Areas, states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. This means that the planet moves faster when it is closer to the Sun and slower when it is farther from the Sun, ensuring that the area swept out over a given time period remains constant.
