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.
MV Dunedin Star
The new ship was launched on 18 April 1950 as a second and completed that September. She was a turbine steamship, and at was considerably smaller than her predecessor. Unusually for a Blue Star ship, she had only some of her holds refrigerated. Nevertheless, she spent 25 years in service with the Blue Star group.
