Some early explorers thought the first planet of the system to be the third star, because of it blazing light reflected by its sodium-rich deserts.[4] Tatooine had a strong presence in the Force, which led the Infinite Empire of the Rakata to the Tatoo system. The collapse of their empire in 25,200 BBY caused the system to be left alone for some millennia. The Galactic Republic explored the segment of the Slice wherein this system was located during the Great Manifest Period and the Indecta Era. By 1,004 BBY, the nearby region belonged to the New Sith Empire, including Hutt Space, a large region of the known galaxy controlled by the Hutt species. After the Seventh Battle of Ruusan in 1,000 BBY the system remained in Hutt control until the reign of the Galactic Empire.[2]
In 1 ABY, the Tatoo system was put under Imperial curfew by a Nameless Moff. Ackmena, the bartender of Mos EisleyCantina on Tatooine, was the one to receive the message, who reluctantally reponded by singing to her gust to leave.
The game Star Wars: Rebel Assault shows an asteroid field right outside or near Tatooine. Although this isn't a contradiction, the field doesn't appear in any other official source. However Star Wars Galaxies shows an asteroid field near Tatooine.
In real life, twin suns in a star system is possible, and actually a common occurrence throughout the universe.
