Wow, look at this:

I wonder what role would play the increased earth weight after doing this for a few hundred years, or if it even plays a role.

 

Very, very little.

The earth's mass increases by about 150'000kg per day from space debris.

Saying that... It sounds really cool and something which would certainly aid with exploration of space.

 

150 tonnes a day! Is that right?

150 tonnes sounds like a lot of micrometeorites etc every day.

 

They are not all micrometeorites. There was a fireball over California the other day.

A meteorite has to be pretty sizable to hit the earth surface but that does not mean it is small.

Still, I don't know what the real number is. I've always heard several tons.

 

I was just talking earlier about science fiction becoming fact. This sounds a little like the plot of Armageddon (bruce willis).

 

Not really, though in the last year we have had at least on asteroid wander within the orbit of the moon. It is very common.

I think it would be cool if we could get one or two in high earth orbit, or lunar orbit, for harvesting. None of the material ever need get close to earth.

I have seen people talking about making the Earth weigh more, the Earth is huge. The numbers for tones compared to the mass of the Earth are less than nanoscopic.

 

Unless the earth's hollow of course.

It wouldn't this is how the earth was formed. Without the astroids you have no planets. Also they say astroids are how we got most of our water, since so many comets/astroids have ice cores.
