Random Constellation Generator

 
Constellation generated locally in your browser with the Web Crypto API.

The 88 IAU constellations

Generate one random constellation from the 88 modern constellations recognized by the International Astronomical Union, with its official three-letter abbreviation, celestial hemisphere, and brightest star (e.g. Orion (Ori) — Equatorial · Rigel). Useful for astronomy lessons, stargazing prompts, observation challenges, and quiz seeds.

Fair random selection

Each result is selected with browser randomness from the fixed set of 88 IAU constellations. Rangdom uses the Web Crypto API for random generation so the next result is not predictable from previous results.

When to use it

Use this generator for astronomy teaching prompts, stargazing and observation challenges, quiz questions, games, and fixtures where a single random constellation is enough.
