What physical law states: When an object nears a massive celestial object in space, it is attracted to its gravity
Newton's law of universal gravitation utters that every giant particle in the universe. Proportioned mass also catch the attention of masses external to its surface, even close up...
F12 is the force applied on object 2 due to object 1 ... While Newton was able to make his law of gravity in his massive work...
There is always some gravitational force between masses. The amount of the force is inversely proportional to the square of the separation distance, and proportional to the product of the masses.
Neither particle has to be "massive" or "giant" and they do not have to be "near" for the gravitational attraction force to exist.
