Yarith sector, named after Lady Yarith Figg, contained several systems of the Greater Javin area of the Outer Rim. It bordered the Javin sector, and shared a jagged border with the Anoat sector designed specifically to check ambitions in both sectors. Anoat sector and Yarith sector were jointly called the Twin Nebulae sectors. Yarith sector was the location of the Kiax Nebula.
The sector capital was Isde Naha, located on the extreme lower edge of the sector.
