@auburnjunky: I think our Sun started with iron in it, which came from previous supernovas. iirc it's the nova itself, or the "last phase of a star`s life" which makes the heavy elements.
@TheZigRat: How would we know how old a planet is? In another system I mean. We (mostly) know how old they are in our system. That would be a very interesting thing to read!
