A binary star system was a solar system configuration consisting of two stars. The term twin suns was also used on occasion to describe binary star systems. Examples of such systems include the Tatoo, Montross, and Mon Calamari systems, as well as the Dalnan system and the system containing the planet Halcyon. While some planets within these systems experienced perpetual daylight, others maintained a typical day-night cycle. On Dalna, the intense brightness from its two suns could induce sun sickness in visitors unaccustomed to such conditions.
During 2 BBY, [Maul](/article/maul], the former Sith Lord, journeyed to Dathomir, his homeworld, alongside Ezra Bridger, a Jedi Padawan, to execute an ancient ritual intended to merge their minds and exchange information. Through this ritual went, they discovered that Obi-Wan Kenobi, a Jedi Master, was in hiding on a planet with twin suns and that he possessed the key to the Sith's destruction. Using this information, Maul eventually located Kenobi on Tatooine; however, he was compelled to lure Bridger there when his attempts to provoke Kenobi proved unsuccessful. Kenobi then decisively defeated the weakened Maul in their last confrontation.
