There would be no life on planet earth and it would totally dark

Answer 2

If there were no gravitational pull from the Sun, Earth would continue its motion in a forward direction. It would not orbit around the Sun. There would be no day and night. There would be no seasonal changes. It would probably collide with other objects in space. It would also not be able to maintain the Moon’s orbit.
