Tarod IX was the formerly inhabited ninth planet in its star system. The system was located in Sector 30 on the United Federation of Planets side of the Romulan Neutral Zone. This was the home of a Federation outpost. 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-D 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")
