According to Kepler’s Second Law of Motion, the correct statement is:
It is constant for equal times.
This means that a planet sweeps out equal areas in equal times, regardless of its distance from the sun. As a result, the speed of a planet changes depending on its distance from the sun, moving faster when it is closer and slower when it is further away, but the area covered in equal time intervals remains constant.
