What is the source of centripetal force that a planet requires to revolve around the Sun? On what factors does that force depend?

(N/A) The source of the centripetal force required for a planet to revolve around the Sun is the gravitational force exerted by the Sun on the planet.
According to Newton's law of universal gravitation,this force $F$ is given by the formula $F = G \frac{M \times m}{r^2}$,where $M$ is the mass of the Sun,$m$ is the mass of the planet,$r$ is the distance between them,and $G$ is the universal gravitational constant.
Therefore,the force depends on the product of the masses of the planet and the Sun $(M \times m)$ and is inversely proportional to the square of the distance $(r^2)$ between them.
