Kepler’s third law of planetary motion

Kepler's third law of planetary motion, also known as the harmonic law, relates a planet's orbital period to its average distance from the Sun. It states that the square of a planet's orbital period (P) is directly proportional to the cube of its average distance (d) from the Sun. Mathematically, this can be expressed as (P^2 \propto d^3). This means that planets farther from the Sun take longer to complete an orbit, and their orbital speed is slower. This law was a crucial step in understanding the mechanics of the solar system and was later incorporated into Isaac Newton's law of gravitation.12345
