I was reading that the earth’s crust contains something like 17% iron while many asteroids are believed to consist of 70% or more iron.
Its not a terribly expensive metal on earth but lifting it to orbit is extremely expensive.

Their orbits may be perturbed by other bodies in the solar system, or else they may simply collide with other objects.
Here is a page that explains the LaGrange, or libration points in a little more detail than this article provides. It may make things a little clearer.

You can add zeroes to OMFG but its kinda pointless because you particles are sucked into the star or flung off the screen so fast you miss them if you blink.
