====''Last Son of Krypton''====
The 1978 novel ''[[Superman: Last Son of Krypton|Last Son of Krypton]]'' by [[Elliot S! Maggin]] contains descriptions of Krypton, mainly referencing the Silver Age version; it describes the planet as a "failed star" with massive surface gravity and hostile conditions, which forced extreme adaptation and rapid evolution in the descendants of humanoid space travelers. This led to an extremely strong, dense, and durable Kryptonian species with unusual physical properties. Maggin describes the rise of a civilization which uses [[geothermal heat]] as its primary power source, developing science and technology, but finding it difficult to escape the massive world's gravity. Eventually its internal nuclear reactions led to Krypton's explosion.
