If a rocket was shot into outer space and never collided with any planets or asteroids, what would happen to the rocket once it ran out of gas? Explain your reasoning

According to Newton's First Law: An object at rest tends to stay at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force.

When a rocket runs out of gas, forces are unbalanced, it slows down, stops at the highest point of its flight, and falls back to earth.
