About galaxy names

Real galaxies are named in three ways, and the best fictional galaxy names borrow from all three. The oldest names describe what astronomers saw through the eyepiece: the Whirlpool, the Sombrero, the Cigar, the Black Eye, the Cartwheel. The second convention is the catalogue designation (M31, NGC 4414, IC 1101, Arp 220), which sounds cold and technical and suits hard sci-fi or a survey ship's logbook. The third names galaxies after their discoverers or the constellation they sit in: Bode's Galaxy, Hoag's Object, the Sculptor Dwarf, the Fornax Dwarf.

When inventing a galaxy for a novel or campaign, combine a descriptor with a morphological word: spiral, barred spiral, elliptical, lenticular, irregular, dwarf, ring, cloud. "Kestrel Spiral" or "Cetus Lenticular" sounds like something a real survey would log, while "Serpent's Coil" or "Drowned Lantern" sounds like a name explorers gave it after seeing it up close. Larger structures (clusters, superclusters, filaments, walls, voids) give you scale beyond a single galaxy, and naming those after mythic primordials such as Ymir, Tartarus, or Ouroboros fits the immensity.

This list mixes genuine catalogued galaxies with invented ones that follow those same rules, so you can pull a real name for grounding or a fictional one for uncharted territory. It also holds quasars, star streams, spacer slang and the Milky Way's names in other languages.

How to choose galaxy names

  • Use catalogue-style names (IC 1101, Arp 220) when a scientist character is speaking, and descriptive names (the Sombrero, the Whirlpool) when a pilot or civilian is.
  • Attach a morphology word such as spiral, elliptical, dwarf, or ring so the name carries information about the galaxy's shape.
  • For a home galaxy that many cultures share, give it several names: the formal survey name, a mythic name, and a slang name used by spacers.
  • Real galaxies turn up in fiction all the time, but if your plot depends on a galaxy's properties, check the actual object so hard-sci-fi readers don't catch a mismatch.
  • Save primordial names (Ymir, Tartarus, Ouroboros) for superclusters and voids where the sense of scale justifies them.

Frequently asked questions

How are real galaxies named?

Most carry a catalogue designation such as M31 (Messier), NGC 224 (New General Catalogue), or IC 1101 (Index Catalogue). Bright or unusual ones also pick up nicknames based on their appearance (Sombrero, Whirlpool, Cartwheel) or their discoverer (Bode's Galaxy, Hoag's Object).

What is the difference between a galaxy, a cluster, and a supercluster?

A galaxy is a single gravitationally bound system of stars. A cluster is a group of hundreds to thousands of galaxies, like the Virgo Cluster, and a supercluster such as Laniakea is a collection of clusters spanning hundreds of millions of light-years.

Can I use real galaxy names like Andromeda in my game or book?

Yes. Catalogue designations and long-standing names such as Andromeda appear across countless works of fiction. A few nicknames on the list borrow from books and films (the Eye of Sauron Galaxy is one), so look into those before you build a title on them. Heavily used names like Andromeda also carry existing associations for readers.

How many galaxies should a sci-fi setting have?

Most space operas stay within one galaxy, because even a single galaxy has hundreds of billions of stars. Introduce a second galaxy only if intergalactic travel is central to the story, since it dramatically raises the scale.
