A parsec represented an astronomical measurement of distance, approximately equal to 30.5 trillion kilometers (or 3.26 light-years). Navigators aboard starships utilized a coordinate system that relied on a scale using 15-parsec increments to chart the positions of star systems. As an illustration, the distance between Tatooine and Geonosis was less than one parsec, while the Kamino system was situated twelve parsecs to the south of the Rishi Maze.
In the era of the Clone Wars, the importance of the planet Toydaria grew as it provided a way to circumvent the Separatist blockade of Ryloth, owing to its location 2000 parsecs nearer to the Ryloth system compared to the closest Republic fleet.
Han Solo asserted that his starship, the Millennium Falcon, completed the Kessel Run in "under twelve parsecs," thereby flaunting its capacity to endure riskier, shorter paths through hyperspace. The truth is that the Falcon's successful navigation of the Run in fewer than twelve parsecs was only technically accurate, requiring rounding down to match Solo's claim.
