Neptune is a ball of gas and ice, probably with a rocky core. There`s no way you could actually stand on the surface of Neptune without just sinking in. However, if you could stand on the surface of Neptune, you would notice something amazing. The force of gravity pulling you down is almost exactly the same as the force of gravity you feel walking here on Earth. The gravity of Neptune is only 17% stronger than Earth gravity. That`s actually the closest to Earth gravity in the Solar System. Neptune has 17 times the mass of Earth, but also has almost 4 times larger. This means its greater mass is spread out over a larger volume, and down at the surface, the pull of gravity would be almost identical. Except you`d sink right in
