Here's why:
* Newton's Law of Universal Gravitation: This law states that the gravitational force 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 Law: The "inverse square" part is crucial. This means that if you halve the distance between two objects, the gravitational force between them increases by a factor of four (2 squared). If you reduce the distance to one-third, the force increases by a factor of nine (3 squared).
In short, the closer two objects are, the stronger the gravitational attraction between them.
