Well theres so much material in the Expanded Universe including a book called "Death Star" that tells the story of the Rebel Alliance victory from the perspective of people who worked there. So, I would just have to assume that they went over the specs/dimensions/weight of the Death Star at some point.

I hope that Randal from Clerks is credited in the author's acknowledgements.

That page itself has conflicting reports of the size. At the top it says "Size: 160 kilometers in diameter," but lower on down the page, it says "The Death Star was 120 kilometers in diameter."

My 'A Guide to the Star Wars Universe' is telling me the first one was 120 km, and the second one was 160 km.

GRAVITY_DEATH_STAR_I clearly tells us they are only concerned with the first death star...not the second.

Future versions of Android may feature GRAVITY_DEATH_STAR_II
