Stellaria
by lua_xvv
Stellaria lets players chart constellations in the night sky, with 80+ constellations spread across six galaxies and a Starbook to record discoveries.
What it does
Discoveries are saved per world, so a constellation charted in one save stays charted there. Each galaxy is fresh and adds its own section to the Starbook, and the constellations carry unique names and short descriptions that give the history a bit more depth. Stellaria is client-side, which means a player on a vanilla or modded server can join without installing anything else. Shaderpack support lets the sky work alongside Iris Shaders.
Server owners who want a shared sky can add the optional Stellaria-Paper plugin. It synchronizes lunar events and constellations across multiple users, so a player sees the same constellations whichever server they last logged in to. Without the plugin each player's sky is mapped on their own client.
The mod is published for Fabric only, for 26.2, and is released under the MIT License but is not open source. The latest Fabric file is 2.0.0 for 26.2, dated 2026-10-14. Mod Menu is optional and useful for managing settings in-game.
