Delta Aurigae III was a planet in or near Federation space in the mid-23rd century, in the Delta Aurigae star system. Circa 2252, the USS Enterprise was en route to Delta Aurigae III to pick up Science Officer Yu. (TOS - Constellations short story: "Chaotic Response")

Delta Aurigae III is referenced only in a hallucinatory memory of Spock's, and thus some details may only be the invention of his imagination.
