In the Federation standard system of planetary classification, a class H planet or moon was characterized as usually being uninhabitable by Humans, but viable for Sheliak. Such a planetary body could contain an atmosphere consisting of oxygen and argon. (VOY: "Scorpion, Part II") The explosive clancium oxide was not recommended for use in Class H environmental conditions. (TNG-R: "Night Terrors")
In the Treaty of Armens, "unwanted lifeforms inhabiting H-class worlds may be removed at the discretion of the Sheliak Corporate." Tau Cygna V was an example of such a planet. (TNG: "The Ensigns of Command")
In 2374, acting captain Chakotay planned to relocate a group of Borg drones, including Seven of Nine, from USS Voyager to a class H moon in the Delta Quadrant. (VOY: "Scorpion, Part II")
