Had not considered the fission of super-heavy elements. A worthwhile point. Cheers.

Its a very creative theory but there is no evidence (other than asteroid density) to support it. First, we have lots of samples from asteroids in our meteorite collection. There have been no findings of any super heavy transuranic elements. None. How could a segregation mechanism create one...

Think of the hundreds (thousands?) of Falcon X launches needed to get the asteroid to the earth. Rocket launches are not green events. Also think of all the other toxic elements (lead, thallium, cadmium etc) that need to be dealt with. Separating the ones you want and dealing with the ones you...

Given that we have many samples from metallic asteroids already on earth, the compositions are very well known. Mostly nickel/iron, but there are relatively large amounts of rare metals such as gold, platinum, etc. Which does make these types of object theoretically valuable. However, as far...
