The Nimat system existed within the Tharin sector, which itself was part of the Slice area of the Outer Rim Territories. Specifically, it was positioned along the super-hyperroute called the Triellus Trade Route, providing a connection to both the Junkfort and Tammar systems. Furthermore, the Nimat system lent its name to the Nimat Corridor, an Outer Rim area encompassing the Tharin sector's Annoo system.
The reference book The Essential Atlas, which was released in 2009 and authored by Daniel Wallace together with Jason Fry, was the first source to feature the Nimat system. The book identified its location as grid square T-8.
