The Stennaros system, a star system, was situated within the Har Worlds sector of the Expansion Region. Within this system resided the planet known as Stennaros.
This system, Stennaros, made its debut appearance in the source article "Shape-shifters" for the roleplaying game. Pablo Hidalgo authored this piece, which was published in the twelfth issue of Star Wars Adventure Journal, a magazine by West End Games, in February of 1997.
Initially, the article positioned the Stennaros system and its planet within the Stennes sector. However, in June of 2015, Jason Fry, who co-authored The Essential Atlas, revealed that Lucasfilm requested the omission of the sector's name from The Essential Atlas Online Companion to prevent any ambiguity with the Stenness Node. Consequently, Stennaros was reassigned to the Har Worlds sector within the Expansion Region.
