How do I install Planetarium?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

The listing gives Minecraft 26.1, 26.1.1, 26.1.2. This is the version stated by the author or source site, not something we verified ourselves.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

No Forge!

If using Quilt, use QSL/QFAPI; if using Fabric, use FAPI; or if using (neo)Forge, use Sinytra Connector + Forgified FAPI.

About

Planetarium simply renders the solar system planets in Minecraft's skybox during the night. In a way, the MC skybox is a planetarium if you think about it. The planet textures are made by @Crackers0106 (PR #1) and @lxly9 (PR #2).

FAQs

Q: Can I use Planetarium with Shaders?
A: Planetarium has been tested with Complementary Shaders and it works as long as you set the Sun/Moon Style to Reimagined.

Q: (1.21+ only) Can I configure what planets are visible and/or their sizes?
A: Yes, by making a datapack containing planet JSONs and textures.

Planet JSONs go in src/main/resources/assets/your_mod/planetarium/planets
Planet textures go in src/main/resources/assets/your_mod/textures/planetarium/planets
Optionally, texture overrides can be done as shown here.
An example planet pack can be found here.

Q: Can I port Planetarium to another MC version?
A: Yes, as long as those ports are not for (neo)Forge.

Q: Can I port Planetarium to another modloader?
A: No, you cannot port Planetarium to a modloader that isn't Quilt or Fabric such as (neo)Forge, or another non-Quilt/Fabric modloader.
