The Weight of the Moon and Other Interesting Facts

The moon in the night sky is the biggest object that we can see with our naked eyes. People love to look at the moon, we plan our garden planting by the moon, and we cut our hair according to the phases of the moon. 

We know a lot about our moon, but there are still a lot of things we can learn about it too. 

How Much Does The Moon Weigh?

Moon Over the Sea at Night

The moon is estimated to weigh about 100,000,000,000,000,000,000,000 pounds. That is a huge amount of weight. If you find that mind-boggling consider the fact that the moon is one-quarter the size of the earth and has about 1% of the mass of earth.

Men have been mesmerized by the moon forever. We even conquered the distance so we could travel to the moon and investigate it more closely.


  • The moon has a radius of 1,079.6 miles or 1.737.5 km
  • The diameter of the moon is 2,159.2 miles or 3,475 km
  • The moon has a surface area of 14.6 million square miles or 38 million square km
  • The moon is less than a third of the width of the earth

Moon Seas

As man explored the moon we discovered that it has craters all over it. Some of those craters were likely caused by impacts from meteoroids or asteroids. Astronauts found dust on the moon that was left there by comets and asteroids.

The maria are the dark areas on the moon that resemble water from a distance. They are simply different types of craters.

Moon Gravity

The amount of gravity that is found on the moon is about 16.6% of the amount that we have on earth. That is why on the moon things float and astronauts have to wear special weighted boots to keep them from floating away when they are walking on the surface.

If you can run and jump for a distance of ten feet on earth you will be able to jump for a distance of sixty feet on the moon.

Does Everything Float Away?

Moon Above the Mountains

Everything that is left on the moon by humans visiting does not necessarily float away. Astronauts have lefts tools and debris.

There are more than 70 “spacecraft vehicles” that have been abandoned on the moon.

There is also food, human waste, and other things we have left there. Humans cannot visit anywhere without leaving evidence of our having been there, and unfortunately, the evidence is often sad pieces of trash and waste.

Far Away

If you measured the distance between the earth and the moon by placing objects the same size as the earth in a line until you reached the moon you would need to line up about 32 earth to reach the moon.

Scientists have noticed that each year the moon gets about 4cm farther away from the earth.
