Quizplus · Accepted Answer

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 implies that the planet moves faster when it is closer to the Sun and slower when it is farther from the Sun, reflecting the varying speed of the planet in its orbit.
