A planet name generator creates names for fictional worlds. In real astronomy, the International Astronomical Union approves planet names: Solar System planets mostly honor Roman gods, while exoplanets are labeled with their star's name and a letter, like 51 Pegasi b.
A good fictional planet name hints at what the world is like — a soft, green-sounding name for a garden world, a harsh one for a desert, a vast, stormy one for a gas giant — and fits a naming system your readers or players can follow, such as numerals for order from the star.
Muxgen's Planet Name Generator offers exactly 15,776 names across eight planet types, with numerals, epithets, star systems, and exoplanet-style catalog designations, screened to avoid famous fictional and real planets. It runs locally in your browser with no account.
Three steps from empty starfield to a charted system.
Pick Earth-like, ocean, desert, jungle, ice, lava, gas giant, ancient ruins, or all types.
Use name only, name + numeral, name + epithet, numeral + epithet, star system, or catalog, and choose 1–50.
Copy your favorites and arrange them into star systems for your map.
Every control in the tool and how it shapes your planet names.
Earth-like, ocean, desert, jungle, ice, lava, gas giant, ancient ruins, or all eight.
Name only, name + numeral, name + epithet, numeral + epithet, name + star system, catalog designation, or any.
Generate 1–50 names per run for a single world or a whole sector.
Turn duplicates off for a clean list; the readout shows the exact unique count.
The building blocks of a believable world.
160 invented names — 20 per type, from Verdaya to Ozymar.
I to VIII, marking order from the star in sci-fi style.
64 nicknames like the Goldilocks World and the Diamond Rain World.
64 invented host stars, from Altor to Zandor.
32 survey codes with star numbers and planet letters b to g.
Famous fictional planets and real Solar System names are left out.
Eight world types, each with its own sound, epithets, and stars.
Temperate, habitable worlds — Verdaya, Kaelora III, the Second Earth.
Planet-wide seas — Maridra, the World Without Shores; Nautilia II.
Dunes and twin suns — Kharos, the Twin-Sun World; Qadira.
Overgrown green worlds — Sylvara, the Breathing Planet; Orchira V.
Frozen and silent — Cryonis, the Ice-Locked Ocean; Nivara VII.
Molten and volcanic — Pyrrhos, the Tidally Locked Furnace.
Storm-banded giants — Jovara, the Ringed Colossus; Zephyron VI.
Dead precursor worlds — Ozymar, the Dust of Kings.
Real worlds behind the planet types and formats in the generator.
First exoplanet found around a Sun-like star, in 1995 — a hot Jupiter.
The nearest known exoplanet, about 4.2 light-years away.
Seven Earth-sized planets around one small, cool star, announced in 2017.
A super-Earth in its star's habitable zone, nicknamed Earth's cousin.
A scorching super-Earth often described as a possible lava world.
Named for the Greek sky god after Herschel's King George name failed to stick.
Named by 11-year-old Venetia Burney in 1930; a dwarf planet since 2006.
Jupiter's moon, with a likely ocean beneath its icy shell.
Three layers that place a world on the map.
The world's identity — what its people or explorers call it.
Its place in the system or its reputation — IV, the Garden World.
Where it is on the star map — the Altor System, HZ-318 b.

Why a type-aware planet tool beats random syllables.
Random syllables ignore what a planet is like. These names fit their world type.
That tool sorts by sound style; this one sorts by planet type and system format.
Chat often repeats Tatooine-like names. Pools skip famous fictional planets.
Real designations belong to real stars. Invented survey codes avoid confusion.
Planet naming traps that break immersion.
Kharos and Kharon in one system confuse readers — vary first letters.
Titan or Europa already mean something to every astronomy fan.
A soft garden name on a lava world sends the wrong signal.
Unpronounceable names stall readers; keep it sayable.
If numerals mean order from the star, keep IV beyond III.
Real systems are mostly hostile — mix gas giants and ice worlds in.
What this tool is and is not.
Names are assembled from curated pools screened against famous fictional planets.
Survey codes are invented and do not refer to real stars or planets.
Astronomy notes are short summaries; see NASA and the IAU for detail.
Muxgen is not affiliated with NASA, the IAU, or any franchise.
Generation runs in your browser. Copy results into your own notes; nothing requires an account.
