Answer:
Kepler's third law is founded on a mathematical formula that is based on the inverse relationship between a planet's orbital velocity and its distance from the Sun.
Explanation:
According to Kepler's third law of planetary motion, the square of period of orbit of a planet (P) is directly proportional to the cube of distance from the Sun (a).
\(P^2=\frac{4\pi^2 a^3}{GM}\)
It was derived from equating gravitation force with centripetal force:
\(\frac{GMm}{a^2}=\frac{mv^2}{a}\)
There is inverse relation between orbital velocity (v) and its distance from the sun (r)
