Planets orbit the Sun in elliptical orbits due to gravity.
Planets orbit the Sun in elliptical orbits due to gravity.

When the planet gets closer to the Sun it will speed up and therefore the area swept by the radius vector must increase.

Answer 1

The first option: "The area swept by the radius vector for a planet must be equivalent for equal time intervals."

(Kepler’s Second Law: a planet sweeps out equal areas in equal times — so it moves faster when nearer the Sun and slower when farther away.)
