Tatoo II
From Wookieepedia, the Star Wars wiki.
Tatoo II, also known as G2, was an orange star at the heart of the Tatoo system. A binary star, its partner was Tatoo I. Children on Tatooine would often tell stories of huge, powerful dragons that would live inside the two great suns that would shine down upon them. Smaller cousins of these dragons were to live in the fusion furnaces that powered many types of machinery and vehicles.
