Orion (planet)
From Memory Alpha, the free Star Trek reference
Orion was the homeworld of the Orion species. The planet's system was in the Orion sector. (TNG: "Conspiracy")
The planet Orion once harbored a highly-advanced civilization whose history has drawn great interest from Federation historians and archaeologists alike.
During the mid-23rd century, noted Federation archaeologist Dr. Roger Korby translated medical records from the Orion ruins that helped revolutionize modern immunization techniques and were required reading at Starfleet Academy. (TOS: "What Are Little Girls Made Of?")
In 2269, through the assistance of the Guardian of Forever, Starfleet officers Captain James Kirk, Commander Spock and historian Lieutenant Erikson traveled to the dawn of Orion's civilization to view the planet's history unfold firsthand. (TAS: "Yesteryear")
Devna, an Orion trapped in Elysia told Kirk that she wished to return through the time barrier and see Orion again. Kirk offered to take her back with him, but she declined, stating that she had accepted where she now was in life. (TAS: "The Time Trap")
In 2372, Ferengi entrepreneur Quark attempted to smuggle kemocite on a highly-profitable side trip to Orion under the guise of taking his ship, Quark's Treasure, on a test flight to Earth. This proved to be unsuccessful due to sabotage. (DS9: "Little Green Men")
