Answer:
Kepler's third law of planetary motion
Step-by-step explanation:
Kepler's third law of motion gives the relationship between a planet’s distance from the sun and the amount of time it takes the planet to orbit the sun. Its formula is given by :
![T^2=(4\pi ^2)/(GM)a^3](https://img.qammunity.org/2020/formulas/physics/high-school/7t44g2krvxnp9tv883p9fmtza478s6rmaa.png)
Where
T is the time taken by the planet to orbit the sun
M is the mass of sun
G is the universal gravitational constant
a is the distance of planet form the sun
