Here's why:
* 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.
* Inverse Square Relationship: The "inverse square" part is crucial. This means that if you double the distance between the objects, the gravitational force between them becomes four times weaker (2 squared = 4). If you triple the distance, the force becomes nine times weaker (3 squared = 9).
In simpler terms: The farther apart objects are, the weaker the gravitational pull between them becomes. This is why you don't feel a strong gravitational pull from the Sun, even though it's massive, because you're very far away from it.
