Original Series
Daran V
A Class-M Federation planet with a population of 3,724,000. In 2268, the U.S.S. Enterprise NCC-1701 was sent to divert what was thought to be an asteroid on a collision course with the planet. The asteroid actually turned out to be the multigenerational spaceship Yonada, built 10,000 years earlier by the Fabrini to save their race before their sun went nova.[1]

Beta Orionis System
Beta Orionis was the “true” Rigel, a bright blue binary system located 773 light years from the Sol System. The system had at least seven planets, including Rigel VII, and was located in the Beta Quadrant.[2] Rigel VII was first visited by Humans in 2254.[1, 2]

Beta Rigel System
Star system with at least ten planets located in the Deneva Sector of the Beta Quadrant, named for its apparent proximity to the “true” Rigel, Beta Orionis, as viewed from Earth.[2] The system was first visited by Humans in 2151.[1] Planets include Rigel VI and Rigel X.[2]

Planet, Class-Q
Variable. Age ranged from 2-10 billion years. Diameter was 4000 to 15,000 km. Typically located in the Hot Zone, Ecosphere, or Cold Zone of a planetary system. Surface ranged from molten to water and/or carbon dioxide ice, due to eccentric orbit or variable output of parent star; atmosphere ranged from tenuous to very dense.[1]

Planet, Class-P
Exo III (TOS-09)
Exo III Surface (TOS-09)
Andoria Surface (ENT-90)
Glaciated. Age ranged from 3-10 billion years. Diameter was 10,000 to 15,000 km. Typically located in the Ecosphere of a planetary system. Water ice covered 80% or more of the surface area, atmosphere consisted of nitrogen, oxygen, and trace elements. May have contained hardy vegetation, animal life, and possibly humanoids.[1]

Planet, Class-N
Reducing. Age ranged from 3-10 billion years. Diameter was 10,000 to 15,000 km. Typically located in the Ecosphere of a planetary system. High surface temperatures due to greenhouse effect; water existed only as vapor. Atmosphere was extremely dense, consisting mostly of carbon dioxide and sulfides. No known native life forms.[1]

Planet, Class-M
Earth (ENT-78)
Vulcan (TOS-34)
Terrestrial. Age ranged from 3-10 billion years. Diameter was 10,000 to 15,000 km. Typically located in the Ecosphere of a planetary system. Surface water was abundant; if water or ice covered more than 80% of the surface, the planet was considered Class O or Class P. Atmosphere was primarily primarily nitrogen, oxygen, and trace elements. Contained extensive vegitation and animal life.[8] Capable of supporting carbon-based, humanoid life.[1]
The designation apparently stemmed from the Vulcan word “Minshara,” which was used to designate planets capable of supporting life.[7] Class-M planets could vary widely in color, cloud cover, and overall appearance. Most Class-M planets were characterized by a relatively thin, tectonically active crust floating on a molten rock mantle, which in turn surrounded a liquid metal outer core and a solid inner core composed of metal crystals.

Planet, Class-K
Mars (STSC)
Mudd (TOS-41)
Adaptable. Age ranged from 4-10 billion years. Diameter was 5000 to 10,000 km. Typically located in the Ecosphere of a planetary system. Surface was barren, with little or no surface water, atmosphere was thin and mostly carbon dioxide. Adaptable for humanoid colonization through the use of pressure domes and terraforming. May contain primitive single-celled organisms.[1]

Planet, Class-J
Jupiter (ENT-50)
Saturn (TNG-101-102)
Gas giant. Age ranges from 2-10 billion years. Diameter is 50,000 to 140,000 km. Typically located in the Cold Zone of a planetary system. Surface radiates some heat and is tenuous and comprised of gaseous hydrogen and hydrogen compounds, atmospheric zones vary in temperature, pressure and composition. May contain hydrocarbon-based life forms.[1]

Rigel XII (TOS-03)
Rigel XII Surface (TOS-03)
Desert. Age ranged from 4-10 billion years. Diameter was 8000 to 15,000 km. Typically located in the Hot Zone, Ecosphere or Cold Zone of a planetary system. Surface was hot and arid, with little or no surface water, atmosphere may contain heavy gases and metal vapors. May contain drought- and radiation-resistant plants and animal life.[1]
