Gravity is an invisible force that pulls objects toward each other. It keeps us on the ground and planets orbiting the Sun. The bigger an object, the stronger its gravity, which is why Earth’s gravity is greater than the Moon’s. On the Moon, astronauts can jump higher because its gravity is weak. Gravity also keeps stars, planets, and galaxies in place. Without it, everything would float aimlessly in space. Gravity is one of the fundamental forces of the universe.
