Tatooine is a fictional terrestrial planet from the Star Wars universe which orbits a set of binary stars. By considering the classification of its Suns, Tatoo I and Tatoo II, and the planets orbital period we were able to find the radius of Tatooine’s orbit, 1.15 Au. It was then possible to work out the varying solar constants for Tatooine depending on its position relative to both Suns, allowing us to calculate an average daytime temperature range of 42.3 celcius to −10.7 celcius.
