Kepler's second law states that "A line between the planet and the sun covers equal areas in equal times." This means that a planet moves faster when it is closer to the sun and slower when it is farther away, resulting in the area swept out by the line connecting the planet to the sun being constant over equal time intervals.
Which does Kepler’s second law state about planetary motion?(1 point)
