Astronomical Event Name Generator
Used by developers, writers, and creators worldwide.
An astronomical event name generator is the fastest way to produce catalog-style designations for fictional deep-space phenomena — supernovae, pulsars, nebulae, black holes, and more. Real observatory catalogs follow strict conventions: a prefix identifies the survey, followed by numbers or coordinates that locate the object. This generator mimics those patterns using prefixes like NGC, PSR, and GRB, then appends invented alphanumeric strings. The result reads as authentic without duplicating any object that actually exists. Filter by event type — Star, Galaxy, Nebula, Black Hole, or Comet — and generate up to a batch at once so you can compare rhythm and prefix style before committing. A hard sci-fi novel, a space RPG star map, and a planetarium script all need different naming conventions, and the type selector keeps you consistent.

How to use
- Choose your options above
- Click Generate
- Copy your result
Detailed instructions
- Select an event type from the dropdown — choose a specific category like Supernova or Nebula, or leave it on Any for mixed results.
- Set the count field to how many names you need in one batch; start with 8-10 to give yourself options.
- Click Generate to produce your list of catalog-style astronomical event names instantly.
- Scan the output for names whose prefix type, numeric length, and overall rhythm match your project's tone.
- Copy individual favourites directly from the list, or regenerate the full batch until a strong candidate appears.
Use Cases
- •Naming fictional supernovae and pulsars in a hard sci-fi novel's appendix star catalog
- •Populating a procedurally generated star map in Unity or Unreal with plausible object IDs
- •Building alien civilisation star charts for a Pathfinder or D&D 5e space-opera campaign
- •Writing planetarium show scripts that reference fictional discovery events by catalog designation
- •Creating fake deep-sky catalog entries for an astronomy classroom exercise on naming conventions
Tips
- →Combine a GRB prefix name with a discovery date suffix in your fiction to make news-style headlines feel more credible.
- →If names feel too random, filter by a single type and regenerate until the numeric strings are short — two or three digits read as older, more famous discoveries.
- →Mix prefix types deliberately: use PSR names for navigation beacons and NGC names for visible landmarks to give your world internal consistency.
- →Avoid using more than two or three distinct prefix types in a single setting — real catalogs specialise, and too many prefixes makes a universe feel inconsistent.
- →For game databases, generate in batches of 10, keep the five strongest, and repeat until you have a full roster rather than accepting every name from one run.
- →Pair a generated name with a common-noun nickname in your writing — 'PSR J1748-2446 (the Ember Needle)' — which is exactly how real astronomers informally label notable objects.
FAQ
do these names match any real astronomical objects in NASA or SIMBAD databases
No — every designation is entirely invented. The generator copies the structural format of real catalogs (prefix plus numeric string) but randomises all numbers, so there is no risk of accidentally referencing an actual catalogued star, nebula, or black hole. You can safely use them in published work without cross-checking any database.
can I use generated names in a published book, game, or film commercially
Yes. All output is free for personal and commercial use with no attribution needed. Because the designations are fictional constructs with no tie to any real space agency dataset or trademarked catalog, there are no copyright conflicts to worry about.
what do prefixes like NGC, PSR, and GRB actually mean
NGC stands for New General Catalogue, a 19th-century survey of deep-sky objects still in active use. PSR identifies known pulsars, and GRB labels gamma-ray burst events logged by space observatories. Pairing these familiar prefixes with invented numbers is what makes the output feel scientifically plausible to readers who know their astronomy.
