Tarod IX was the ninth planet in the Tarod system. The system was located in Sector 30 on the United Federation of Planets side of the Romulan Neutral Zone. Prior to stardate 41986, a Federation outpost had been established on the planet. This was one of nine outposts located in this sector.
In 2364, Tarod IX was the second stop of USS Enterprise-D on its tour of the destroyed outposts in Sector 30. Near this system, on its passage to the next destroyed outpost, the Enterprise made contact with a Romulan D'deridex-class warbird. (TNG: "The Neutral Zone") It was later determined that the outpost had been attacked and destroyed by the Borg. (TNG: "Q Who")
