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.
Death's Head
After the initial "Transformers" storylines, the character appeared in "Doctor Who Magazine" #135 (Apr. 1988), in a story which saw him reduced from a giant robot to a more human stature, by means of "one of the Master's Tissue Compression Eliminators." He then made a guest appearance in Marvel UK's "Dragon's Claws" #5 (Nov. 1988), which led into an ongoing series of his own. The first issue prompted a letter from Stan Lee, praising the character and creative team, but a variety of factors, such as distribution and "Death's Head"'s smaller size ('US format') causing it to be obscured by larger comics, meant the comic was cancelled at #10.
