Every object with mass exhibits a field of gravity around it. Something like a magnetic field. The strength of the field diminishes as the distance from the object increases. Thus the gravitational force increase as we approach the object and vice versa

As you might know, Newton's universal law of gravitation says that Every object in the universe is attracted towards every other object with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them. That is, if the mass of the two objects in question is high, the gravitational pull between them is high too. On the other hand, as the law states that the gravity is inversely proportional to the square of the distance between them, greater the distance, lesser the gravity. In other words, As you increase the distance, the gravity decreases.
Consider this example: What would happen to the gravity between two objects if you doubled their distance?
Ans: The gravity increases by 4 times!
i.e, if you consider the distance to be "d", twice would be 2d.If that is squared, you get 4d^2.
Is the concept clear?
