Uranus is the third biggest planet in the Solar system. It is so big that you could fit 63 Earth-sized planets into it.

So that must mean that Uranus has a very strong gravity pull, right?

Actually, you’ll be surprised to know that the gravity of Uranus is weaker than Earth’s gravity. How is that possible when the planet is so massive?

Well, the answer is that the mass of the gas planets is distributed across a greater volume, and as a result, these planets have very low density, and therefore, a lower gravitational acceleration. Here’s a fun fact. Due to all this, Uranus and Venus have almost exactly the same gravity.

So, how much would you weigh on Uranus?

Below you will find a calculator that can answer that for you with precision. But before we get to that there’s something that must be clarified.

A person can’t stand on the planet Uranus because the planet is made out of gas. It does not have a solid surface to walk on. If you were to “fall” into the planet, you would keep sinking until you reached its core because nothing would stop you. That is, assuming that you could find a way to survive the low temperatures, crushing pressure, supersonic winds, and toxic environment, but that’s a subject for another time.

So, for the purpose of this exercise, if you wanted to calculate how much would you weigh on Uranus, we will need to imagine that the planet does somehow have a solid surface. With that clarification made, let’s proceed.

In this imaginary Uranus-like planet, you would weigh approximately 10% less than your current weight on Earth.

A person who weighs 70 kilograms (154 lbs) on Earth would weigh approximately 63.3 kilograms (139.5 lbs) on Uranus.

On top of that, to walk on this imaginary planet with the mass of Uranus, you would have to add up the weight of the spacesuit required to survive.

To give you an idea of how heavy astronaut suits are, the spacesuits that the Apollo astronauts used to walk on the Moon weighed about 163 kilograms (360 pounds) on Earth. On the Moon that weight was reduced to just 27 kilograms (60 pounds) which is still a lot, but it is manageable. However, on Uranus, the weight of this equipment would not be reduced considerably and would be much harder to carry around.

To precisely calculate your weight on Uranus, you can use a simple rule of three that factors in the difference between the force of gravity on both planets.

The following calculator simplifies the process.

Weight on Uranus formula

The formula to calculate your weight on Uranus is as follows:

WUranus = (WEarth / 9.81) * 24.79

WUranus: Weight on Uranus

WEarth: Weight on Earth

The other two numbers are the force of gravity on each planet and it is given in meters per square second (m/s2). The force of gravity on Earth is 9.81 m/s2 and on Uranus, it is approximately 8.87 m/s2.
