Answer:
Gravity is the force which helps the objects to remain in their place. In space, it helps the planets to revolve or rotate in their orbits. Gravity holds the planets together in the galaxy. It facilitates the planets to revolve around the sun. Gravity depends upon the mass of the body. The more the mass of the body, the more the gravitational force. The inner planets have less gravitational force than the outer planets. On the other hand, the Gravitational pull is stronger in the inner planets than the outer planets.
