Tarod IX was the ninth planet in a 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")
