    Step into the exoplanet hall

    The codex opens onto a gallery of exoplanet names drawn from twenty thematic slices: hot Jupiter, super-Earth, rocky terrestrial, gas dwarf, ice giant, lava world, ocean world, and the long tail of star, system, and discovery. Each scroll in the antechamber holds a name that sounds like a world you can chart on a star map. Roll the dice to summon an exoplanet, conjure several to compare tone, or wander deeper into the bestiary to find the world that fits your story.

    How the codex works

    Every click of the dice calls a new exoplanet name from the scribes' pool. The well is hand-tended for hard sci-fi novelists, indie TTRPG players, fanfic writers, and educational writers. The generator is free, instant, online, and never asks you to sign up. Re-roll until a name lands, then mix two or three results to layer star, system, and discovery into a fuller alias.

    What lives in the hall

    By star and system

    Many exoplanet names anchor in a star and system: Tau Ceti, Proxima, Epsilon Eridani, Trappist, Kepler, Gliese, Wolf, the inner zone, the habitable zone, the outer zone, the rogue cloud. Choosing one star gives a planet a foothold before any story is told.

    By type, era, and discovery

    Other names gather tone from type: hot Jupiter, super-Earth, rocky terrestrial, gas dwarf, ice giant, lava world, ocean world, tidally locked, tidally heated. The right type depends on your tale: low-level colonist, mid-campaign colony, late-game exodus, indie TTRPG, novel arc, NaNoWriMo draft.

    By voice, pun, and label

    Layer a voice over the planet: bureaucratic, mythic, scientific, civic, archival, poetic, classical. The right tone depends on your story: classic hard sci-fi, modern myth, indie game, fanfic, NaNoWriMo draft, novel manuscript.

    For hard sci-fi writers and game masters

    Hard sci-fi novelists, indie TTRPG players, fanfic writers, and educational writers reach for these exoplanet names for colonies, exploration missions, alien outposts, and habitable-zone expeditions. Novelists and fanfic writers of generation-ship epics, terraforming fiction, and alien-contact tales will find the same well open. NaNoWriMo drafts, homebrew campaigns, and one-shots all benefit from a fresh world drawn on demand.

    Tips for choosing

    • Pick one anchor and let it carry the name: a star, a type, a system, or a voice.
    • Mix registers deliberately; bureaucratic labels and mythic handles can coexist.
    • Treat the type as a hook: one strong prefix beats three soft ones.
    • Keep the rhythm short: two to four words lands hardest on a star map.
    • Read the name aloud at your gaming table to test its weight.

    Common questions

    • How many exoplanet names can I conjure from the codex?
    • Can I steer the result toward a star, a type, or a system?
    • Are the names free to use in published novels and zines?
    • Do these names work for fanfic, indie TTRPGs, and educational writing?
    • Can I save the names I like for later sessions?

    Scribes ask…

    Can I really use these exoplanet name names for free?

    Yes. Every name rolled with the Exoplanet Name Generator is free to use in your stories, games, streams or projects — no credit required, though a kind word is always welcome. Just remember the muse is generous, so the occasional name may already belong to someone else; double-check before tattooing it on a logo.

    Is there a limit to how many exoplanet name names I can roll?

    Roll until your dice catch fire. The codex holds many hundreds of exoplanet name names for this generator alone, and the pool gets shuffled on every visit, so you'll rarely see the same line-up twice.

    Does this work without an internet connection?

    Once a generator's page has loaded, the names are cached in your browser. You can reroll on a train, in a tent, or deep in a dungeon — no signal required.
