There's not much else to add at this point. I'd love if someone could bring Dr. Astro's attention here, so far he has completely ignored this thread.

The astronomical data for observation of Gog given in the book might as well be a red herring, the author admitedly introduced errors in the book to hinder its credibility, due to the horrendous nature of the claims made.

But anyway Dr. Astro's opinion on the characteristics of Gog given in the book could be interesting.
