# Planet Name Generator

Generate planet names grounded in catalog codes, mythology, alien phonics, or colonial shorthand, each with a note on what it signals

Category: Creative

## Prompt template

```
I'm naming a planet for a science fiction story, tabletop campaign, or worldbuilding project and need a batch of names that fit the setting.

The planet is a [PLANET_TYPE:select:habitable earthlike world,hostile or toxic world,gas giant,ice or frozen world,desert world,ocean world,artificial or constructed world].

For the naming convention, I want [NAMING_CONVENTION:select:scientific catalog style like a real star designation,mythological or classical,invented alien-language style,human colonial naming].

Generate [COUNT:number:5-20] planet names that fit this type and convention. For each one, add a short one-line note on what the name signals about the world: its danger, its history, who named it, or what a traveler would expect on arrival. Vary the structure and length across the list so a catalog-style batch doesn't collapse into the same three-letter-and-number pattern, and a mythological batch doesn't recycle the same handful of god names. Keep the tone of [PLANET_TYPE] consistent with the convention: a hostile toxic world under catalog naming should read colder and more clinical than the same world named in an invented alien language. After the list, pick your top 3 and explain what makes them stand out.
```
