Like its neighbor Neptune, Uranus likely formed closer to the Sun and moved to the outer solar system about 4 billion years ago, where it is the seventh planet from the Sun. We refer to this special acceleration as the acceleration caused by gravity or simply the acceleration of gravity. Planets like Uranus or Neptune, which much less hydrogen and helium - probably not as much, but for gas giants and most stars, gravity very likely increases . The surface gravity on Uranus is about 86% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 86 pounds on Uranus (assuming you could find someplace to, well, stand).
