Most of the time in various ST series, they are traveling to planets or at least star systems to locations there. Certainly there are space stations and the like, but these all appear to be orbiting stars or planets. Are there any locations in Star Trek that are visited regularly but are not specifically part of a star system?

EDIT: It seems that the difficulty of this question lies in the definition of "regularly". My original intention was indeed "regularly visited on screen, perhaps more than 3 times in 3 separate episodic arcs", but it seems that there is practically no location that fits this (with the exception of like...Earth or Vulcan and the like). As such, I have accepted the answer that has stations visited more than once.

  • K-7 (TOS: The Trouble with Tribbles) didn't seem to be associated with any star system, despite mention of Sherman's Planet. Also, so far as I can recall, the Bajoran wormhole, despite proximity to Bajor wasn't explicitly in the Bajoran star system.

  • I presume visited regularly on screen? For example the buoys in the neutral zone are mentioned, not visited on screen, but somebody must do maintenance on them.

I think it just popped up here yesterday: Deep Space Station K-7, the one from TOS "The Trouble with Tribbles" is not located in orbit around a planet or star. I think the same applies to most of the "Deep Space" stations, though I don't know how many of them (other than K-7 and, obviously DS9) actually appeared.

The Enterprise departs Deep Space Station K-7 in the star-flecked blackness of interstellar space

There's also Starbase 375 where the Federation fleet massed before attacking to retake DS9.

  • Actually any number of research stations are also located at a distance from any potentially inhabitable worlds/star systems.

  • I don't recall the Bajoran wormhole being actually in the Bajoran star system despite proximity to Bajor.

  • The wormhole is well inside the Bajoran system. Commented Sep 12, 2023 at 20:55
  • K7 is only visited twice in canon.

It wasn't "visited regularly" but the Mutara Nebula (converted to the unstable Genesis planet and its star, Wrath of Khan) was, well, a nebula, which tend to be well separated from stars that aren't forming within them.

  • As you say, not visited regularly.

  • Interesting nonetheless and at least tangentially related. Upvoted.
