The Star Wars galaxy is the fictional setting for the Star Wars franchise. It is referred to in several official publications as the Galaxy or the Known Galaxy.
It is unofficially referred to as the Galaxy, Far Far Away (GFFA for short) by the fan community due to the opening crawl from the beginning of each Star Wars film, which contains the line “A long time ago in a galaxy far, far away....”.
Several unofficial sources state that the length of the Star Wars galaxy is 120,000 light-years across and contains 400 billion stars, half of which can support life, and 25 million sentient species in the galaxy.
