The Gertafuu system represented a star system found in the region of Wild Space. A frigid astronomical body known as Gertafuu VI orbited the star at the sixth orbital position. This planet was home to both the sentient Aqualish and Whiphid species.
Jason Fry and Daniel Wallace initially mentioned the Gertafuu system in their 2009 reference book, The Essential Atlas, locating it within grid coordinate S-18.
