## Understanding Kepler’s Third Law Equation

Kepler’s Third Law of Planetary Motion relates the orbital period of a planet to its average distance from the sun. This law, established by the astronomer Johannes Kepler in the early 17th century, is a fundamental principle in the field of astronomy. The equation associated with Kepler’s Third Law allows scientists to calculate the period of a planet’s orbit based on its distance from the sun.

## Kepler’s Third Law Equation

Kepler’s Third Law can be expressed mathematically as:

*T*^{2} = (*k* x *r*^{3})

Where:

*T*is the orbital period of the planet.*r*is the average distance of the planet from the sun.*k*is a constant of proportionality.
