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.
Return of the Jedi: Death Star Battle
The cover art depicts the Millennium Falcon in flight away from the partially constructed Death Star, pursued by four TIE interceptors. It was produced by John Berkey, the noted science fiction artist who designed some of the earliest poster art for the original 1977 film, "Star Wars".
