Iron, steel, nickel and cobalt are magnetic … WebGravity. The force that pulls things to the centre of Earth (and other planets) is called gravity. Gravity also holds Earth and the other planets in their orbits around the Sun. The force of gravity also exists on the Moon but it is not as strong as it is on Earth. This is because the Moon is much smaller than our planet.
