If he asks - Would a sheet of iron rust in a near earth orbit, the suggestion that sheet iron is used in satellite construction should not enter the discussion at all AFAIK

The only suggestion that iron was used in satellites was - or at least it appeared so to me and apparently to everyone else except you - to be a JOKE.

If you don't have the answer, don't give a "near enough is good enough" one, because in space, that will kill you and everyone around you.

It wasn't "near enough is good enough."

It was "something roughly comparable is all we can find hard data for, so we must extrapolate."

Because - you know - nobody uses IRON in NEAR EARTH ORBIT.

YET.
