Detailed explanation-1: -Kepler’s Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits. Basically, that planets do not move with constant speed along their orbits.
Detailed explanation-2: -Kepler’s second law of areas According to this law, “the line joining the planet sweeps out equal areas in equal interval of time". It means that areal velocity is constant.
Detailed explanation-3: -The answer is based on Kepler’s law, which states that a line from a planet to the sun sweeps out equal areas in equal times.
Detailed explanation-4: -According to third law of Kepler, the cube of the mean distance of a planet from the sun is proportional to the square of the periods. This law is also known as Law of periods. It makes a comparison between orbital period and radius of orbit of a planet to those of other planets.
