Tatoo system/Legends

The Tatoo system, also known as the Tatooine system, contained the planet Tatooine which orbited twin suns, Tatoo I and Tatoo II. It was located in Arkanis Sector.

The twin suns of the Tatoo system created premature aging in Humans on Tatooine.

Behind the scenes
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, the Iron Planet, which is truly an asteroid, might well be a part of this field.

In real life, twin suns in a star system is possible, and actually a common occurrence throughout the universe. However, when Star Wars Episode IV: A New Hope was made, this had yet to be discovered, and was assumed to simply be a fictional occurrence.
