A planet will orbit its sun because the gravitational force of the sun pulls on the planet. the gravitational force of the planet pulling on the sun is?

equally strong but acts in the opposite direction. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. Therefore, while the sun's gravity keeps the planet in orbit, the planet also exerts a gravitational pull on the sun, contributing to the mutual gravitational interaction that governs their motions. This interplay ensures that both the planet and the sun influence each other's trajectories in space.
