Planets are classified according to their predominant properties. While there is, at times, overlap in some of the classifications the primary classification of a planet assists travelers through space in identifying the primary characteristics of a planet more easily.
Class A
| Type: | Unknown |
| Age: | Unknown |
| Atmosphere: | Sulfer Dioxide / Carbon Dioxide |
| Radius: | Unknown |
| Surface: | Rocky / Partially Molten |
| Composition: | Igneous Silica / Basalt |
| Location: | Any |
| Habitability: | Unknown |
These planets are generally young, rocky worlds that are rife with volcanic activity. This volcanic activity spews vast amounts of sulfur and carbon dioxide into the atmosphere, causing a greenhouse effect that keeps temperatures relatively hot. Such worlds have tenuous and toxic atmospheres and are unsuitable to any kind of life.
When this extreme volcanic activity eventually ceases, the planet "dies" and becomes a Class C world.
Class A planets are common in the universe; Jupiter's moon Io is a prime example.
Class B
| Type: | Unknown |
| Age: | Unknown |
| Atmosphere: | Oxygen / Sodium / Hydrogen |
| Radius: | Unknown |
| Surface: | Barren / Molten in Places |
| Composition: | Iron / Potassium / Silicon |
| Location: | Hot Zone |
| Habitability: | Unknown |
