    Meteors are leftovers of the same primordial stuff that made up earth, so a cross sample of them would largely share the same ratios as earth, minus the volatiles.

    Though it looks like the community hive mind has made up its mind on this one

      I did some very rough estimates and found that the amount of aluminum entering the Earth’s atmosphere each year is probably between 100 and 500 tons, which would be roughly comparable to the amount coming from these LEO comm sats like Starlink.

      These are just super ballpark figures, but it’s in the same order of magnitude. More research is definitely necessary.
