Septimis Minor (or Septimus Minor) was a planet. It was the original destination of the colony ship SS Artemis in 2274. When the ship's guidance system failed, the ship drifted off course, eventually landing on Tau Cygna V. Starfleet performed an extensive search but failed to discover the fate of the ship. (TNG: "The Ensigns of Command")

In 2371, the location of Septimus Minor was labeled in the star chart Data and Picard were studying in stellar cartography aboard the USS Enterprise-D. (Star Trek Generations, okudagram)

The name of this planet was spelled "Septimis" in the script [1] and on screen in the "Artemis" okudagram, while it was spelled "Septimus" in both the DVD subtitles, the Star Trek Encyclopedia (4th ed., vol. 2, p. 264), in an entry where this location was described as a "planetary system", and on screen in the star chart in "Generations".
