Temperature

Temperature was a measure of the warmth or coldness of an environment or object, expressed in degrees. Its zero point was defined by the freezing point of water.

On the planet of Hoth, the temperature in summer, the hottest season, only crawled up to about 10 degrees below freezing. In contrast, the temperatures on Tatooine were so high that only a small part of the planet's northern hemisphere could sustain intelligent life. The boiling surface of Bespin, a gas giant, bubbled at a constant six thousand degrees.

Frequent orbital bombardments and beam-weapon assaults could affect the atmosphere of a planet to the point of increasing the temperature of that world's seas, potentially killing many of the organisms they contained.

In many living organisms, environmental exposure to excessive heat could cause dehydration, abnormally high body temperatures, mental confusion, and, in the worst cases, death.

The insides of starships such as the Millennium Falcon were carefully temperature-controlled.
