Planetary Classifications

Class C (Chthonian)

ClassE.png

A Class E Planet

Class D (Dead)

Class E (Elastic/Exothermic)

Class F (Frozen)

Class G (Geoinactive)

Class H (Harsh)

Class I (Ice Giant/Neptunian)

Class J (Jovian/Jupiter Gas Giant)

Class K (K'vara)

Class L (Limited)

Class M (Minshara/Habitable)

Gelidic Subtype

Gelidic Class M Worlds are locked into persistently cooler temperatures, creating expanded continental and oceanic glaciation. While not yet a Class P "Snowball Earth," a Gelidic world is near-permanently in an "Ice Age."

Gracilic Subtype =

Gracilic Class M worlds have thin but breathable atmospheres. They may have close-hugging atmospheres with sea-level like conditions that rapidly become unhabitable at higher terrains, or else sea-level atmosphere of the planet is similar to 3,000 meters above sea level on Earth.

Lacustric Subtype

Lacusrtic Class M worlds have most of their surface water locked up in rivers, lakes, and inland seas. Such worlds have very few expansive oceans.

Lutosic Subtype

Crassic Class M worlds have thick atmospheres that usually obscure much of the planet's surface and have increased air pressure. Often these worlds have dense and humid atmospheres. Habitability to a Human comfort level can likely be attained at a higher elevation.

Paludal Subtype

Paludal Class M worlds are noted for having a high percentage of low-lying, near or at sea-level terrain which is often marshy or swampy.

Pelagic Subtype

Pelagic Class M worlds are approaching Class O status and have surfaces dominated by oceans to a degree that 85% of the surface is under water.

Suptic/Cenotic Subtype

These unusual worlds possess Class M environments below the planet's surface- usually in extensive cavern systems. A great deal of the planet's water is subterranean but accessible in nature. The surface of such a world may or may not be condusive to life, but has a breathable atmosphere.

Tundric Subtype

Tundric Class M worlds are not Class P and are not Gelidic, but are prone to or in the process of entering an Ice Age.

Vadumic Subtype

Xeric Subtype

Class O (Oceanic)

Class P (Polar)

Class R (Radioactivity)

Class T (Toxic)

Class V (Variable)

Class W (Water World )

Class Y (Ya'ma/Demon)
