In a graphic created for the Starbase Yorktown command center, but not seen in the final copy of Star Trek Beyond, Cygnus VII was the subject of a planetary survey, located in the Cygnus system. The planet was listed as unaffiliated.
While class M, the survey revealed the planet as having a lethal atmosphere and an habitability index of 17% due to lethal gases. According to the survey, the atmospheric chemistry of the planet consisted of 73.24% nitrogen, 16.49% oxygen, 1.248% argon, 0.57% carbon dioxide, 0.02% neon, and < 0.001% helium. A reference to bathymetry on the graphic implies the planet had bodies of water.
In the Federation database, there were 756 references to this planet.
