The Delphi Ardu system was an uninhabited star system. Outpost 63, a remote base of the extinct Tkon Empire, was located in this system. The Federation had by the mid-24th century charted Delphi Ardu and its planetary system with long-range probes.

In 2364, the starship USS Enterprise-D entered this system in pursuit of a D'Kora-class raider which was alleged to have participated in the theft of a T-9 energy converter on Gamma Tauri IV. (TNG: "The Last Outpost")
