The force of gravity on Uranus is 8.69 meters per second squared, which is also the speed at which dropped objects accelerate toward the surface of the planet. On Earth, objects accelerate at 9.78 meters per second squared. Uranus' gravity is approximately 89 percent of the force of Earth's gravity.
The planet Uranus, which is composed of gases, liquids and ice, has approximately 63 times the volume of Earth. Despite its large size, it has only 14.5 times more mass than Earth, making it a considerably less dense planet. The low gravity on Uranus is a direct result of its low density.
