Answer:
because the gravity gets stronger as the 2 objects get closer. so the 2 are basicly merging
Step-by-step explanation:
Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.
hope this helps!
FUN FACT: we achaly all have gravity, its just so weak that we cant feel it.
