I don't. How much? I'd also be curious to compare that number to: 1. How much we have mined on earth 2. Expectations on how much we expect to mine over time

- seti0Cha 4y agoAccording to Google, the moon's mass is 8.1 x 10^19 tons. According to some random info I found, we mined about 3 x 10^9 tons of metal ore in 2019. If we did that on the moon for a thousand years and brought it all back to earth, that's still 7 orders of magnitude less than the moon's mass, so what is that, 1 ten millionth? Is that significant? Well, the earth apparently gains 4 x 10^4 tons every year from just sucking up space dust, and presumably has been for the entire 4.5 x 10^9 years the moon has been around without obvious issues, so it seems like our moving a bit more mass between them wouldn't do much.
- staticassertion 4y agoThanks. That sounds reasonable.
