# Moon Gravity: Your Weight on the Moon

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 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

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.

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.
