Naming the Infinite
Let’s analyze the categories of science fiction planetary nomenclature and see how to apply them to your space-faring civilizations and star map designs. This guide is part of our comprehensive collection of Places & Worldbuilding, providing deep research to help you craft the perfect identity.
The Three Spheres of Planetary Naming
In any well-developed science fiction setting, planetary names typically fall into one of three administrative categories depending on when the planet was settled, who discovered it, and who currently controls its resources.
1. Scientific Catalog Designations
These are the default names assigned by astronomical surveys before colonization. They consist of a survey prefix (often representing the telescope or corporation that discovered the system) followed by a star catalog number and a lowercase letter indicating the planet’s order from the star. Examples: Kepler-22b, Gliese 581g, Cor-097d. Using catalog designations for frontier worlds or automated mining outposts creates a sense of scientific realism. It signals that the world is not yet culturally significant — it is a resource, not a home.
2. Colonial and Corporate Names
When a planet is colonized, its name typically changes to reflect the corporate sponsor, the colony’s purpose, or a nostalgic reference to Earth (or the homeworld). This produces names like: New Horizon, Hadley’s Hope (from Aliens), Weyland-Prime, Ceres Station, Utopia Planitia. These names are transparently commercial or optimistic, reflecting the ambitions of the settlers and the industrial focus of the colony (e.g., fuel refining, agriculture, or terraforming).
3. Historical and Mythological Names
The oldest, most culturally central worlds in a sci-fi universe bear names derived from classical mythology, historical figures, or alien languages: Mars, Jupiter, Vulcan, Tatooine, Coruscant. These names have shed their descriptive origins and function as pure symbols of power, culture, and history, anchoring the galactic faction’s identity.
Planetary Naming Conventions by Planet Type
| Planet Classification | Naming Strategy / Formula | Example Fictional Name | Atmospheric Connotation and Economy |
|---|---|---|---|
| Habitable / Earth-Like | Nostalgic Earth place-names or Virtue compounds | New Canterbury / Providence | Suggests a clean start, agricultural success, and hope; typically the capital. |
| Gas Giant / Ice Giant | Mythological giants or Scientific coordinators | Titanus / HD-4402 Prime | Suggests immense scale, helium-3 harvesting, orbital gas siphons, and high hazard. |
| Desert / Arid | Middle Eastern phonology or Mineral descriptors | Kharak / Rust-3 | Suggests extreme heat, water scarcity, and rich heavy metal or silicon mining. |
| Oceanic / Aquatic | Maritime myth or Liquid-related compounds | Neptunia / Wavecrest | Suggests water-harvesting platforms, rich aquatic ecology, and marine settlements. |
| Volcanic / Obsidian | Mythological underworld or Heat descriptors | Tartarus / Obsidian-V | Suggests thermal energy extraction, lava flows, and highly dangerous prison colonies. |

Designing a Galactic Naming System: A Worldbuilder’s Guide
To populate a star map with authentic names, follow this system:
- Establish the faction history: Who colonized this sector? If it was a militaristic empire, systems will be named after war heroes or victories (e.g., Bastion, Victory-IV). If it was a corporate conglomerate, systems will bear brand names or catalog IDs (e.g., Apex-09, Weyland’s Drift).
- Create a catalog prefix: Invent 2-3 scientific surveys for your universe (e.g., Gal-Cart, Exo-Net, Sol-Survey). Use these to generate catalog names for unexplored systems.
- Layer the language: If a planet has been held by multiple factions (e.g., originally alien, then colonized by humans, then captured by a rebel faction), it should have multiple names in its records. This naming conflict is a great source of narrative tension.
- Test for scale: Ensure your galaxy has a mix of catalog numbers, corporate names, and ancient mythological designations. If every planet on your map has a cool, descriptive name, the universe will feel small and artificially curated.
Conclusion
Planetary nomenclature in science fiction is not just about choosing cool alien sounds. It is an exercise in administrative cartography — a system that reflects who discovered the world, who settled it, and what they built there. By combining catalog prefixes with corporate, colonial, and historical naming conventions, science fiction writers can create a galaxy that feels vast, populated, and grounded in administrative reality.
Astronomical Nomenclature and Fiction
How do real-world astronomical catalogs influence sci-fi star naming?
Science fiction writers often draw inspiration from real-world scientific naming systems, such as the Bayer designation (e.g., Alpha Centauri) or the Gliese catalog (e.g., Gliese 581). These naming systems combine Greek letters with the genitive form of the parent constellation or catalog numbers, giving names a grounded, scientific texture. By mimicking these patterns—such as naming a system ‘Epsilon Eridani’ or ‘Kepler-186f’—authors create a sense of realism that aligns with modern astrophysics.
What is the narrative function of numbering planets within a system?
In sci-fi, planets are traditionally numbered outwards from their host star using Roman or Arabic numerals (e.g., Prime, Secundus, Tertius, or I, II, III). This structural naming indicates a systematic, space-faring perspective, suggesting that the system has been surveyed and cataloged by a central authority. It also creates immediate dramatic tension when a ship approaches a specific planet, such as ‘Vega IV’, implying a progression of environments from scorching inner planets to frozen outer giants.
How do cultural and mythological naming pools shape alien star maps?
Fictional empires often name stellar systems after their own deities, historical figures, or philosophical concepts, reflecting their values and history. A militaristic alien race might name their systems after battles and conquerors, while a peaceful, scientific faction might choose names related to light, discovery, or harmony. Analyzing the thematic patterns of a star map allows readers to understand the cultural identity and imperial reach of the factions that charted it.

What is the linguistic difference between colonial and indigenous alien star names?
In sci-fi settings, star systems often have multiple names reflecting different histories. A system might have an official, cold alphanumeric name assigned by an interstellar empire (e.g., ‘Sector 4-B’), a descriptive human colonial name (e.g., ‘New Hope’), and an ancient, complex native name used by its indigenous inhabitants. Showing these competing naming systems in dialogue or maps highlights the political tensions and history of planetary colonization.
