Physics and Star Wars
To estimate the effects of the second Death Star, Minton looks into its mass. According to estimated data from some students of Lehigh University, the steel mass needed for building one would be around 770 kilograms times the mass cubed in weight. This would give the Death Star of about ten to the power of nineteen kilograms in mass. Using this data, Minton produces equations that lead him to conclude the fragments would hit the moons surface so hard causing craters almost four times the size of the Chicxulub crater in Mexico. This impact would cause a planetary firestorm and vaporize all lifeforms on the moon.
Endor (Star Wars)
In one of the "Star Wars Tales" comics, an Imperial veteran of Endor refers to the moon being devastated by the impact of falling debris from the Death Star, which was blown up while in orbit around the moon. However, another character dismisses this as a myth, saying that most of the Death Star's mass was obliterated in the explosion, and that the Rebels "took care of the rest."
