Kepler's Third Law states that the square of the orbital period (the time it takes to complete one orbit) is proportional to the cube of the average distance from the sun.
In simpler terms:
* The farther away an object is from the sun, the longer it takes to complete an orbit.
Example:
* Mars is farther from the sun than Earth.
* It takes Mars about 687 Earth days to complete one orbit, while Earth takes 365 days.
Reasoning:
The gravitational force between the sun and a planet decreases with distance. This means that a planet farther away from the sun experiences a weaker gravitational pull. As a result, it moves slower in its orbit and takes longer to complete a full revolution.
