How to Create a Good Planet Name
Match the Environment
Let the planet's environment guide the name. Ice worlds can sound cold and remote, while ocean worlds can feel deep and mysterious.
Readability First
A good planet name should be easy to read and pronounce. Avoid excessive consonants, apostrophes, or random-looking letter combinations.
Consider the Genre
Sci-fi names can use numbers and technical suffixes. Fantasy names benefit from melodic, mythic-sounding syllables. Alien names can be harsher but must remain readable.
Use Scientific Patterns
For realistic names, follow real astronomical conventions: star catalog prefix, number, and orbital letter (e.g., Kepler-442b).
Planet Naming Rules and Tips
Astronomical Naming: Real exoplanets follow IAU conventions — the star name followed by a lowercase letter in order of discovery (e.g., Kepler-442b, HD-209458b).
Mythological Naming: Many fictional planets draw from mythology. Roman, Greek, Egyptian, and Norse mythologies provide rich source material for planet names.
Environmental Naming:Names that reflect the planet's dominant feature — frozen, volcanic, oceanic — help readers immediately understand the world's character.
Genre-Specific Patterns: Sci-fi benefits from technical-sounding designations, fantasy from melodic and ancient-sounding names, alien from unfamiliar phonetics, and realistic from scientific catalog formats.
