Exploring Gravity and the Solar System

What role does gravity play in the formation of planets and stars?

• It repels objects away from each other.

• It attracts objects towards each other, allowing them to form

• It has no effect on the formation of planets and stars.

• It only affects the motion of planets, not their formation.
