In early 2365, the USS Enterprise-D arrived at the planet to take up specimens of plasma plague for transport to Science Station Tango Sierra. At that time, Lieutenant Commander Hester Dealt was the commanding officer of the station. (TNG: "The Child")
According to the script for "The Child", the name of the planet was pronounced "O-det Nine."
The planet model first used here for 'aucdet IX would later be used for Gagarin IV in "Unnatural Selection", Galorndon Core in "The Enemy", Barzan II in "The Price", Jouret IV in "The Best of Both Worlds" and Bilana III in "New Ground". For its appearance as 'aucdet IX, the model had a blue color.
