Kepler's law, called the law, states that planets farthest from the sun take a longer time to orbit it.

Kepler's THIRD law, called the HARMONIC law, states that planets farthest from the Sun take a longer time to orbit it.

Explanation:

As we know that as per Kepler's III law the law of time period says that square of time period of motion of planets around the sun is directly depends on the cube of the distance of planets from the sun.

It is given as

so as per this law of harmonics we can say that planets which are farther away from sun will take more time to revolve around the sun as compare to the planets which are closer to it.
