Class J and Class T
Class J and Class T planets are designated gas giants. Class J are smaller than Class T which are considered "super", or "ultra", gas giants — possibly even brown dwarfs on the verge of becoming stars. Brown dwarfs are sub- stellar objects with a mass below that necessary to maintain Hydrogen -burning Nuclear fusion reactions in their cores as do stars Jupiter and Saturn would fall under Class J-sized gas giant planets. In the Star Trek: Deep Space Nine episode "Starship Down", the USS Defiant entered the atmosphere of a Class J gas giant to rescue the crew of a Karemman ship attacked by the Jem Hadar. " Starship Down " is an episode of Star Trek Deep Space Nine, the seventh episode of the fourth season The USS Voyager encountered a Class T Super-Giant in the Delta Quadrant with "radiogenic" rings in the Voyager episode "Good Shepherd".

Class M
Class M, or "Terrestrial", planets are the most commonly visited planets in the Star Trek series. A Class M planet is a fictional classification of a Planet in the Science fiction franchise Star Trek. They are named after the Vulcan term "Minshara" class. They have atmospheres comprised of nitrogen and oxygen but most importantly, they have plenty of liquid water necessary for carbon-based life to exist. Life is almost always present and is often flourishing as extensive plant and animal life. Usually, a sentient race is also present. Earth is a textbook example of a Class M world. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 Other worlds in the series are mentioned as being Class M planets, such as Vulcan, Cardassia Prime, Risa (initially seen in the Next Generation episode "Captain's Holiday"), Bajor, Betazed, Romulus, and Qo'noS.

Class N
Class N planets have a reducing environment and are barren and rocky with extremely high surface temperatures caused by thick atmospheres containing carbon dioxide and corrosive sulfides. A hydric soil is a soil that formed under conditions of saturation flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part The term sulfide ( sulphide in British English) refers to several types of Chemical compounds containing Sulfur in its lowest Oxidation In this case, Venus could be considered Class N as it has a reducing (corrosive) atmosphere. The VENUS ( V ictoria E xperimental N etwork U nder the S ea project is a cabled sea floor observatory operated by the University In the Next Generation episode "Night Terrors", Class N environments were mentioned as the ideal places to use non-oxidizing explosives. " Night Terrors " is a fourth season episode of Star Trek The Next Generation. However the MS-DOS game Star Trek: The Next Generation - A Final Unity, mentions that Class N planets are more related to Class M, with the key difference being a higher ratio of water to land. MS-DOS (short for M icro' s' oft D isk O perating S ystem is an Operating system commercialized by Microsoft. Star Trek The Next Generation - A Final Unity is a computer game by Spectrum HoloByte, based
Class Y
Class Y planets are referred to as "Demon" worlds, where surface conditions do not fall into any other recognized category. Such worlds are usually hostile and lethal to humanoid life. If life develops on these worlds they usually take on many bizarre forms, like living crystal or rock, liquid or gaseous physical states, or incorporeal, dimensional, or energy-based states. In the series, examples of Class Y "Demon" planets include, Tholia, the "Silver Blood" planet discovered by the USS Voyager in the Delta Quadrant in the episode "Demon" and later mentioned in "Course: Oblivion", and the home world of the incorporeal Medusans.

Other classes
Other planetary classes exist that are designated by all the letters of the alphabet from A to Z (with the exceptions of U, V, and W, which are not used). These other letter designations are considered semi-canon to the series. [1]
- Class A, B and C – Typically small, young planets whose class depends on their age and solidity of their cores.
- Class E, F and G – Typically, Proto-Earth-sized planets whose class depends on their age and solidity of their cores.
- Class I – Class of gas giant, larger than Class J, and smaller than Class S and T.
- Class O and P – Planets covered almost completely with water (class O), or water-ice (Class P).
- Class Q – Planets with continually changing environments caused by peculiar orbits, an orbit around a variable output star, or some other factor which causes conditions to drastically change overtime.
- Class R – A rogue planetary body which is one that does not orbit a star but drifts freely in space.
- Class S – Class of gas giant smaller than Class T and the next larger size up from Class I.
- Class X and Z – Reserved for other designations of "demon" planets.
