J-25 VI was the sixth planet of the J-25 system. This was a Class M planet. Prior to the mid-2360s, this planet was home to a highly industrialized civilization with cities linked by a system of roads. When the Borg attacked, the attacking ships removed cities, which caused rips to appear on the planet’s surface. In 2365, the Federation starship Enterprise scanned this planet. (TNG: "Q Who")
J-25 VI (FGC-J25 VI) was located in the Beta Quadrant. (Star Trek: Star Charts, page 13)
