Detailed explanation-1: -Gravity is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth’s surface. Planets have measurable properties, such as size, mass, density, and composition. A planet’s size and mass determines its gravitational pull.
Detailed explanation-2: -Gravitational force is the force responsible for holding planets in their orbits around the Sun. The Sun contains 99.86% mass of the entire solar system and that is why it is able to keep the planets in their orbits.
Detailed explanation-3: -As the planets began to settle into orbits the pull of gravity from their own center of mass pulled them in on themselves, tugging at each planet’s mass equally towards its center. This strong internal gravitational pull gives planets their round, spherical shape.
