Simoom, the homeworld of the Simoomian sensory hound, existed as a planet inside the Simoom system. This system was situated in the Senex sector of the Mid Rim region of the galaxy.
The first time Simoom was referenced was in the reference book The Essential Atlas. Jason Fry and Daniel Wallace authored this book which was made available on August 18, 2009, and it located Simoom at grid reference L-18.
In our reality, the term "simoom" refers to a scorching, arid, and sand-laden wind found in desert environments.
