The Thurra system, a star system, resided in the Esstran sector of the Outer Rim Territories, specifically within the Trans-Hydian region.
Thurra served as the main star around which the system's celestial bodies revolved. The planet Thule and its moon [Sivvi] were in orbit around it, as were the gas giant [Enenpa] and its collection of forty moons.
In the 2007 publication Jedi vs. Sith: The Essential Guide to the Force, errors are present. The book erroneously presents the Thule and Thurra systems as distinct and separate entities. Furthermore, it incorrectly assigns Dromund Kaas to the Thurra system. Subsequently, the book rectifies this error by correctly locating Dromund Kaas within the Dromund system.
