    1. While the actual numbers may be small, gravitational force is always a constant in the known universe. Even an object as small as an apple would have it's own gravitational force and would be affected by the gravity of planets and stars, as well. The object will subsequently stay with the realm of our solar system (assuming it left from Earth) and ultimately be picked up in the gravitational pull of a planet or moon.
