Septimis Minor

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. 

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 (NCC-1701-D). (, okudagram)
