Detailed explanation-1: -Kepler’s Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit. Thus we find that Mercury, the innermost planet, takes only 88 days to orbit the Sun. The earth takes 365 days, while Saturn requires 10, 759 days to do the same.
Detailed explanation-2: -This comparison takes the form of the ratio of the squares of the periods (T²) to the cubes of their average distances from the sun (R³), finding it to be the same for every one of the planets. Thanks to this law, if we know a planet’s distance from its star, we can calculate the period of its orbit and vice versa.
Detailed explanation-3: -The third law expresses that the farther a planet is from the Sun, the slower its orbital speed, and vice versa.
Detailed explanation-4: -Kepler’s Third Law: The ratio of the squares of the periods (T) of any two planets revolving around the sun is equal to the ratio of the cubes of their average distance (r) from the sun.
Detailed explanation-5: -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.
