Planetarium renders planets in Minecraft's sky during nighttime; similar to how a physical world planetarium functions. The planet textures are made by @Crackers0106 (PR #1) and @lxly9 (PR #2).

I personally welcome third party ports to previous minecraft versions, but I respectfully ask that all third party ports remain Quilt/Fabric exclusive. That means no ports to (neo)Forge or any other non-Quilt/Fabric modloader.
