Planetary Classification Chart

From Terragen Database, the galaxy's most reliable star browser The Planetary Classification Chart or PCC is the categorization table for planets within the Terragen Sphere and it organizes them by their type, inhabitability, natural resources and role in the borders of the dominating space entity. It's used as a fast and quick way to describe a planet within a system and on interestellar maps.

By type
There are 20 ways to classify a planet by its type:


 * S - silicis: S-class planets are rocky planets that are primarily composed of silica (silicates and oxygen). Most notable examples are Earth, Venus and Mars.
 * S class α - silex generis alpha: S-class α planets are rocky planets that are completely covered by water and abundant in oxygen. Another name for this class is oceania planet. These worlds are usually inhabited by microbes or primitive water organisms, and are fairly common throughout the Sphere's territory. It's thought that they are because it's commonly observed that they are in a state when they begin developing life, in a similar way as primitive Earth, so they are also young planets.
 * S class β - silex generis beta: S-class β are rocky planets that are primarily composed of carbon (diamond) and have an atmosphere composed of methane, benzene or ethane. They are easily identifiable for their brown and dark colors. Less than a 25% of the rocky planets in the Sphere are carbon planets, making them veryvaluable for mining-centered empires and corporate empires.
 * S class A - silex generis anulus: S-class A (not to be confused with α) are rocky planets that have a stable ring system around them, usually composed of silicates.
 * U - uxoris: U-class planets are rocky planets that have a similar size, mass and characteristics to those of Earth.
 * So - sororis: So-class planets (not to be confused with any of S) are rocky planets that have a bigger size, mass but similar characteristics to those of Earth. They are also known as superterras.
 * F - filiae: F-class planets are rocky planets that have a smaller size, mass but similar characteristics to those of Earth. They are also known as miniterras.
 * Aa - aridi: Aa-class planets (not to be confused with α or A) are rocky planets that are very dry and have very low humidity. They may have small bodies of water. Another name for this class is oasis planet.
 * T - terform: T-class planets are rocky planets usually orbiting close to their mother star, making them extremely dry and desertic. They rarely possess any life forms. However, thanks to their geography being mostly flat, they are easy to settle in and to terraform, hence their name.
 * L - liquefacti: L-class planets are rocky planets usually orbiting so close to their mother star that they are completely molten. They have orbits that only last few Earth-days and are slowly being consumed by their mother star due their proximity.
 * G - gelus: G-class planets are rocky planets usually orbiting far away from their mother star, making them extremely cold and completely covered by snow or ice. Their geography ranges from being flat to being covered by mountains, glaciers, cliffs and canyons. They are a great source for water and oxygen extraction.
 * Uu - umidi: Uu-class planets (not to be confused with U) are rocky planets that are very humid and that have constant storms. They are, for the most part, covered by dense tall forests, jungles and swamps. They are a great source for biomass extraction.
 * P - pretiosi: P-class planets are planets that have naturally evolved life (without the intervenition of any empire). They can be rocky or gas.
 * M - miraculi: M-class planets are planets that have evolved life through the means of terraformation and intervenition of a galactic empire. They can be rocky or gas.
 * J - jovian: J-class planets are gas giants that have a similar size, mass and characteristics to those of Jupiter.
 * I - imperatoris: I-class planets are gas giants that have a larger size and mass to those of Jupiter.
 * R - reguli: R-class planets are gas giants that have a smaller size and mass to those of Jupiter.
 * Fv - ferventis: Fv-class planets (not to be confused with F) are gas giants that orbit so close to their star that are losing mass constantly, and will end up devoured because of their proximity. They are also known as hot Jupiters or hot Neptunes (depending on their size).
 * Gg - glacialis: Gg-class planets (not to be confused with G) are gas giants far away from their star, usually smaller than Jupiter, also known as ice giants.
 * O - orbis: O-class planets are gas giants that have a stable ring system around them, usually composed of water and ice.
