      Space is an area of zero gravity!

      Yup, there is no gravity in space, that’s why everything floats around like you see in movies. Gravity can be found on the surface of planets, because planets are so large and pull things into them. The strength of gravity varies from planet to planet, and even on the moon. The strength of gravity on earth is about 5 times that of the gravity on the moon- great question!

      Zero gravity in the deep vacuum of space. But anything that has mass has gravity, even tiny gas and dust particles that floats around. You yourself have your own gravitational field! But the effects of this are so unbelievably small you’d never notice. The tiny gas and dust particles need to have a gravitational field, otherwise they couldn’t have clumped together to form the Earth and other planets!

      What these guys said! There’s no gravity in space, the size of an object is what gives it gravity, which is why gravity varies depending on the size of the planet/moon. Our moon is much smaller than earth, that’s why its gravity is so much weaker than here on earth.
