At least 5
The Cophrigin system in the Outer Rim was a star system within the Ash Worlds sector of the galaxy. Containing at least five planets, the fifth of which was a terrestrial world, the system also sported an asteroid belt. Despite the system's relative isolation, many governments annexed the area of space over the millenniums of war and peace and claimed it as their own. During the Galactic Civil War, Imperial agent Mara Jade located the mysterious Jedi Master known as the Dark Woman.
