Detailed explanation-1: -The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.
Detailed explanation-2: -Every object in the universe-stars, planets, moons, even you-has gravity. Gravity is a force of attraction between all objects.
Detailed explanation-3: -The Sun’s gravitational force is like the tetherball rope, in that it constantly pulls Earth toward it. Earth, however, like the tetherball, is traveling forward at a high rate of speed, which balances the gravitational effect. This means that the planet neither flies out into space nor falls into the Sun.
