Planet Classification

Planets of the Future Universe as classified by the scientists of Cradle, based on numerous factors that are very advanced and sciencey. The following is a list of some of the classifications.

• Class A — Uninhabitable, often without an atmosphere. A lifeless planet.
• Class B — Uninhabitable, usually because of a volatile, unliveable atmosphere.
• Class C — Uninhabitable by man, but certain life forms are present.
• Class I — Cradle-like and fully inhabitable. Oxygen-rich atmosphere and water.
  • Naturally Inhabitable (I-NI) — Inhabitable without interference.
  • Artificially Inhabitable (I-AI) — Inhabitable only with external stimuli.
• Class X — Generally disregarded as a planet, more of a "found" or "created" planet. Often home only to extremely specific life forms.
