Feasibility paper here:
https://kiss.caltech.edu/final_reports/Asteroid_final_report.pdf

Wouldn't it be better to return an asteroid to an Earth-orbit (or high earth orbit) instead of a Lunar orbit, due to the influence of the Earth's gravity on that of a 3-body problem?
In other words, a small asteroid orbiting The Moon would likely get tugged by the gravity from Earth, thereby disrupting the Asteroid and causing it to:
* Crash into the moon
* Become destabilized and fall out of Lunar orbit
* Require constant propulsion/adjustments, thereby costing more in energy and fuel usage

Or, because the asteroid would small (likely in the range of 1,000,000kg) it would be small enough to be "parked" in a orbit and asteroid mining could be conducted.

Do you have a point?
Or are you another anti-science nigger, shitting up a pro-science image board?

Hopefully some non-retards will show up in the thread.

How do you mine, refine and smelt anything without gravity?

Nuclear powered lasers for melting asteroid material/metals, and then pouring the molten material into forms that cool.
It will take an insane amount of research to make asteroid mining viable.

Asteroids have a small amount of gravity.
Other than that I have no idea.

It's so difficult to mine and process ores on asteroids that for all intents and purposes it is currently impossible with current technology. I don't want to discourage you but instead to encourage you to come up with solutions. However you need to be aware of the inherent problems, like negligible gravity, the risks from kicking up huge clouds of debris, the negligible gravity, getting any infrastructure to adhere to the surface, the negligible gravity etc.

Sure, you could build a centrifuge and put processing equipment inside it (so expensive it would make the whole process uneconomical) but even then how do you get material into the centrifuge without gravity.

Anything we can move is too small to be practically mined and will pose great risks to Earth. Moving asteroids is even more pointless and dangerous than traveling to an asteroid and harvesting resources in situ so you can take the refined materials to where they are needed.

The reason you can't mind asteroids OP is because they don't exist. The earth is flat with a dome.
