In the Star Wars universe, the exact size of the galaxy is not explicitly defined. However, it is generally accepted that the Star Wars galaxy is much smaller than the real-life Milky Way galaxy.
The Star Wars galaxy is often described as a "galaxy far, far away," suggesting that it is located outside of our own galaxy. In terms of size, it is commonly understood that the Star Wars galaxy is significantly smaller than the Milky Way.
The Milky Way galaxy has a diameter of approximately 100,000 light-years and contains hundreds of billions of stars. On the other hand, the Star Wars galaxy, as depicted in the films, books, and other media, appears to be relatively compact, consisting of a few hundred star systems and planets that are the primary focus of the story.
It's important to note that the Star Wars galaxy is a fictional construct, and the exact size and scale are not precisely defined within the franchise. The focus of the Star Wars stories is primarily on the characters, conflicts, and events taking place within a limited portion of the galaxy, rather than providing a comprehensive representation of its entire size.
