How to name a planet

A planet name gets repeated more than almost any other name in a sci-fi or space-fantasy campaign: it's the mission briefing, the distress call, the line on the star chart your players circle in red. That means it has to survive being said in a hurry. Good planet names are short, a little strange, and built to stick after one hearing, often leaning on hard consonants and clipped syllables (Vorash, Krenn, Xantor) or a colder, technical cadence, because those sounds read fast under stress and land as otherworldly rather than ordinary.

The Planet Name Generator forges names in that mold by default: tight two-part builds like Zethora, Vexirn or Krelas that sound plausible whether you're naming a mining outpost, a dying homeworld, or the next stop on a hyperspace route. Instant mode is free and immediate, perfect for improvising a system on the fly. Arcane mode uses AI to go further, giving each planet a short, table-ready hook you can drop straight into a session.

This generator works just as well outside hard sci-fi. D&D and other tabletop settings are full of planar and "other world" fantasy: the Astral Sea, the Feywild, distant planes a party might be flung into by a portal or a wild magic surge. Those places want the same qualities as a planet name - short, strange, memorable - so treat this as a generator for any world beyond your own, sci-fi or otherwise.

Forge a batch, read the results aloud, and keep the ones that sound like somewhere your players would actually want to go, or flee.

Frequently asked questions

Pair a short, hard-edged root with a tight, exotic ending: something like Vor + ash, or Zeth + ora. Keep it to two syllables where you can, favour clipped consonants (K, X, V, Z, T) over soft ones, and say the result aloud. If it sounds plausible shouted over a comms channel, it works.
A good planet name is short, easy to say under pressure, and a little strange without being unpronounceable. It should sound distinct from every other name in your setting, since players will repeat it constantly across a campaign. Avoid long compound names or excess apostrophes; the best ones fit in a single breath.
Examples include Vorash, Krenn, Xantor, Zethora, Nyrix, Quoral, Skorrun and Ilarath. Notice the pattern: a hard or exotic opening sound (Vor, Kre, Xan, Zeth) fused to a short, punchy ending (-ash, -orn, -ix, -ora). Forge a batch above to generate hundreds more, with AI-written lore if you want it.
Sci-fi planet names often lean colder and more technical, sometimes edging toward designation-style names (Xar-9, Ordos Prime). Fantasy planet names lean more mythic, closer to a place name in an epic than a star chart entry. In practice the two overlap heavily, and the same short, hard-consonant approach works for both.
Yes. Outer planes, the Astral Sea, the Feywild, and any 'world beyond your own' that a party might travel to want the same qualities as a planet name: short, strange, and memorable. Use this generator whenever you need a name for somewhere that isn't part of your campaign's home continent.
