Class A - Gas Supergiant

Planets of this class are usually found in a star's outer or "cold zone". They are typically 140 thousand to 10 million kilometers in diameter and have high core temperatures causing them to radiate heat. Low stellar radiation and high planet gravity enables them to keep a tenuous surface comprised of gaseous hydrogen and hydrogen compounds.

Class B - Gas Giant

Class B Planets are usually found in a star's outer or "cold zone". They are typically 50 thousand to 140 thousand kilometers in diameter and have high core temperatures but do not radiate much heat. Low stellar radiation and high planet gravity enables them to keep a tenuous surface comprised of gaseous hydrogen and hydrogen compounds.

Class C - Reducing

Planets of this class are usually found in a star's "habitable zone". They are typically 10 to 15 thousand kilometers in diameter. They have high surface temperatures due to the "greenhouse effect" caused by their dense atmospheres. The only water found is in vapor form.

Class D - Geo-plastic

Planets of this class are usually found in a star's "habitable zone". They are typically 10,000 to 15,000 kilometers in diameter. They have a molten surface because they have been recently formed. The atmosphere contains many hydrogen compounds and reactive gases. Class D planets eventually cool, becoming class E.

Epsilon Indi 3, Excalbia.

Class E - Geo-metallic

Planets of this class have a molten core and are usually found in a star's "habitable zone". They are typically 10,000 to 15,000 kilometers in diameter. Their atmospheres still contain hydrogen compounds. They will cool further eventually becoming class F.

Class F - Geo-Crystalline

Class F planets are usually found in a star's "habitable zone". They are typically 10 to 15 thousand kilometers in diameter and have surfaces that are still crystalizing. Their atmospheres still contain some toxic gases. They will cool eventually becoming class C, M or N.

Delta Vega 2, Vega 4.

Class G - Desert

Planets of this class can be found in any of a star's zones. They are typically 8 to 15 thousand kilometers in diameter. Their surfaces are usually hot. Their atmospheres contain heavy gases and metal vapors.

Class I - Asteroid / Moon

Planetary bodies of this class can be found in any of a star's zones. They are usually found in orbit of larger planets or in asteriod fields. They are typically 100 to 1,000 kilometers in diameter. They have no atmospheres. Their surfaces are barren and cratered.

Class J - Geo-Morteus

Planets of this class are found in a star's "hot zone". They are typically 1,000 to 10,000 kilometers in diameter. They have high surface temperatures due to the proximty to the star. Their atmospheres are extremely tenuous with few chemically active gases.

Class K - Adaptable

Planets of this class are usually found in a star's "habitable zone". They are adaptable for humanoid colonization through the use of pressure domes and other life support devices. They are typically 5,000 to 10,000 kilometers in diameter. They have thin atmospheres. Small amounts of water are present.

Class L - Geo-Inactive

Planets of this class are usually found in a star's "habitable zone" or "cold zone". They are typically 1,000 to 10,000 kilometers in diameter. Low solar radiation and minimal internal heat usually result in a frozen atmosphere.

Class M - Terrestrial

Planets of this class are found in a star's "habitable zone". They are typically 10,000 to 15 thousand kilometers in diameter. They have atmospheres that contain oxygen and nitrogen . Water and life-forms are typically abundant. If water covers more than 97% of the surface, then they are considered class N.

Class N - Reducing

Class N planets have a high surface temperature due to the greenhouse effect. Water can only exist as vapor. The atmosphere is extremely dense, made up mainly of carbon dioxide and sulfides.

Venus

Class O - Pelagic

Class O planets are usually found in a star's "habitable zone". They are typically 10,000 to 15 thousand kilometers in diameter. They have atmospheres that contain oxygen and nitrogen . Water and life-forms are typically abundant. If water covers less than 80% of the surface, then they are considered class M.

Argo, Ascella, Canopus 8, Deneb 3.

Class P - Glaciated

Water or ice covers over 80% of the Class P planet surface. It is habitable for humanoid life, but only while wearing extreme cold weather gear. The atmosphere is similar to Class M, and there is little to no plant or animal life except around the equator.

Exo III.

Class Q - Variable

Planets of Class Q have almost no sense to them. Icecaps could be located at the equator and tropical rainforests may appear at the north and south poles. Planets of this type were once Class M or similar, however they sometimes have an erratic orbit that changes their climates constantly. Life may exist onthe planet, but nothing can evolve due to the severe and sudden climate changes that happen on the surface.

Genesis Planet.

Class R - Rogue

Rogue planets are planetary bodies that no longer orbit a star. They may have once, but they are normally cast out of a star system due to gravitational instability. The surface can vary greatly. While it will be cold due to having no star, geothermic activity is usually extensive, and given the right atmosphere, heat may be contained on the surface and make it habitable. These planets are incredibly rare however, and only 2 have ever been confirmed to exist.

Class S - Near Star

Planets of this class are usually found in a star's "cold zone". They are typically 50 million to 120 million kilometers in diameter and have high core temperatures causing them to radiate heat and light. These are the largest possible planets, because most planetary bodies that reach this size do become stars.

Class T - Gas Ultragiant

Planets of this class are usually found in a star's "cold zone". They are typically 10 to 50 million kilometers in diameter. They have high core temperatures causing them to radiate enough heat to keep water in a liquid state.

Bruedon Epsilon 5, Optima Alpha 5.

Class U - Marginal

The Class U planet has little to no surface water, but has a habitable atmosphere. It is suitable for colonization, but aquafiers are needed to sustain the colony. The atmosphere is oxygen/argon, and carbon dioxide reasings are high. The planet can be terraformed, but the lack of water makes that a very difficult job.

Class V - Unlisted

Class V Planets have no definition as of yet

Class W - Unlisted

Class W Planets have no definition as of yet

Class X - Unknown

The term "Class X" is used to classify a planet that fits no known category. It is usually a temporary title until the Federation Science Council can fit the planet into an existing category, or create a new one with the planet in question's specifics.

Class Y - Demon Class

Planets and planetoids of this class can be found in any of a star's zones. They are typically 10 - 15 thousand kilometers in diameter. Atmospheric conditions are often turbulent and saturated with poisonous chemicals and thermionic radiation. Surface temperatures can reach in excess of 500 K. (Starfleet Note: Communication is frequently impossible, and transport may be difficult. Simply entering orbit is a dangerous prospect. No known environment is less hospitable to humanoid life than a Class Y planetary body.)
