Star Name Generator
Used by developers, writers, and creators worldwide.
A star name generator produces plausible star and exoplanet designations in the formats real astronomers use, from Bayer designations like Alpha Centauri to catalog entries like Kepler-452 and HD-40307. Whether you are writing science fiction, building a space game, or teaching how stars are catalogued, you need names that feel authentic rather than made up out of nowhere. This tool mixes Greek-letter-plus-constellation names with real catalog prefixes and exoplanet suffixes to generate designations that look like they came from a star chart. Choose how many you need and generate a batch. It is ideal for sci-fi authors, game designers, educators, and worldbuilders. The names are fictional and will not match real catalogued stars, but they follow genuine naming conventions, so they lend instant credibility to a fictional galaxy or a classroom example of stellar nomenclature.

FAQ
how are real stars named
Stars carry several names: traditional names, Bayer designations (a Greek letter plus the constellation, like Beta Lyrae), and catalog numbers (HD, HIP, Gliese). Exoplanets add a lowercase letter, as in Kepler-452 b. This generator mirrors those conventions.
are these real star names
No — they are fictional designations that follow real naming formats. They will not match actual catalogued stars, so use them for fiction, games, and teaching examples rather than as references to real astronomical objects.
what is a bayer designation
A Bayer designation names a star with a Greek letter indicating its brightness rank within a constellation, plus the constellation's Latin genitive — Alpha Centauri is the brightest star in Centaurus. It is one of the oldest systematic star-naming schemes.
