Moon Gravity: Your Weight on the Moon

Moon Gravity Facts

What is the moon’s gravity?

The gravity of the moon is 1/6 of Earth. So if you stepped on a scale on the moon, you could subtract 83.5%.

For example, that means 100 kg in weight would be 16.5 kg on the moon. Talk about a weight loss plan!

If you want to calculate how much you weigh on the moon, take your weight and divide it by 6.

The moon’s unusual atmosphere

Despite popular belief that the moon can’t hold onto an atmosphere, it actually consists of sodium and potassium.

Yet these gases cannot be found in Earth’s atmosphere, Venus or Mars.

It’s because the moon’s gravity pulls in these gases which gives it an atmosphere.

That means that a lack of atmosphere means the moon’s surface gets very hot (117°C) when facing the sun.

But it also gets cold (-153°C) when facing away from the sun.

The Moon’s gravitational pull on Earth keeps it steady

Giant Impact Hypothesis

The giant impact hypothesis sums up the formation of the moon. It had a tremendous impact on stabilizing Earth’s climate.

For example, the gravitational pull from the moon on Earth helps prevent it from wobbling. In turn, this prevents climate swings and wild temperature shifts.

Finally, the giant impact collision tilted Earth on its axis. Ultimately, this tilt is the primary cause of seasons on our planet.

What is the Moon’s Gravity?

The gravity of the moon is 1/6th that of Earth. If you stepped on a scale in the same location, it would read 83.5% less than what it does here.

If you are interested in learning more about the moon or outer space in general, then be sure to check out these online courses. There is a variety of universities that offer these programs from around the world so it’s easy to get started today.

If you have any questions or comments about the moon’s gravity, please do not hesitate to let us know what’s on your mind. We would love to hear from you.


  1. Hello, Darrell Lovins. What you have said is inaccurate. We can use ‘weight’ to mean the amount of stuff we are made of; and we can use it to mean a force. Words are our servants, not our masters. They have no intrinisic meaning. We each use them to mean certain things. It’s arbitrary, although there is broad agreement in each walk of life. If a layperson says to another layperson that he weighs 90kg he is correct (assuming his mass, as you would see it, is actually 90kg). If you say you weigh, on Earth, approx. 900 N, you are correct (assuming your mass is, as you would see it, 90kg). It doesn’t help the spread of science to be arrogant about language. A better approach would be to simply point out that physicists, for example, mean one thing by a certain term, and laypeople mean another. Shalom.

  2. The example you provide is inaccurate.
    1. Kilogram is a measure of mass, not weight. The number of molecules in the person’s body does not change due to the person’s location. Only the force applied to those molecules does.
    2. The metric measure for weight is the Newton (N). 100 kg is approximately 981 N. Or, 100 kg is approximately 220 lbs.
    3. Mass does not change, weight however does.
    4. Mass (kg) and weight (lbs) are often used interchangeably, though this is incorrect.
    5. Yes, we determine mass by weighing objects.
    6. I suspect the example was simplified as your target audience might not have had the background necessary to appreciated the discriminatory details.
