Kepler’s second law states that B. 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, ensuring that the area swept out by the radius vector in a given time interval is constant.
Which does Kepler’s second law state about planetary motion?
A. Planets move at the same speed at all points along their orbit
B. A line between the planet, and the sun covers equal areas and equal times
C. The square of the orbital period is directly proportional to the cube of the semi-major axis
D. The planet travels along an elliptical orbit
