The fundamental force responsible for keeping the planets in orbit around the sun is gravity. Gravity is a natural phenomenon that attracts two bodies towards each other, depending on their masses and the distance between them. In the context of our solar system, the sun’s massive gravitational pull draws the planets into elliptical orbits, maintaining their stability over time. Understanding gravity is crucial not only for astronomy but also for understanding many physical processes that occur in the universe, from the motion of celestial bodies to the behavior of objects on Earth.
