The cosmos (or universe) collectively refers to all celestial bodies and locations in the Metroid series (aside from locales in other dimensions or voids).
Ordering System
The ordering of the cosmos roughly from largest to smallest is as follows:
- Galaxy
- Nebula
- Cluster
- Sector
- System
- Region
- Asteroid Belt¹
- Planet
- Moon
- Station
In the rankings below, many designations are unknown, so the headings are done by the most general information known.
