* Newton's Law of Universal Gravitation: This law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* Mass: The Sun is significantly more massive than the Moon. In fact, the Sun's mass is about 333,000 times greater than Earth's mass, and the Moon's mass is only about 1/81 of Earth's mass.
* Distance: While the Moon is much closer to Earth than the Sun, the Sun's sheer mass outweighs the distance factor.
In simpler terms:
* The Sun's massive size creates a much stronger gravitational pull on Earth than the Moon, despite the Moon's closer proximity.
Therefore, the gravitational force between the Sun and Earth is much stronger than the gravitational force between the Moon and Earth. This is why Earth orbits the Sun, and the Moon orbits Earth.
