Planetarium

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?
