About this project
What does Celestial Exploration add?
A mod for exploring beyond our own planet and into the outer reaches of space!
This is not meant to be a hyper-realistic mod! My goal was to keep the general style and gameplay of vanilla Minecraft the best I could, but with outer space. And some creative liberties, of course.
This is mod is still being updated! Sometimes updates might take a while though.

Submit an issue on the Github!
Will you update the 1.16.5 version? / Will you do any backports?
No, sorry.
Will you update to 1.19+?
Maybe. Right now my focus is on fully completing the 1.18.2 version. After that, we’ll see about an updated version…
What about a port to Fabric/Quilt/etc?
No, sorry.
Is Pluto a planet? Will Pluto get its own dimension? What about exoplanets/dwarf planets/etc?
Check out the wiki to see what my plan is for the mod, but right now, my focus is on the main solar system. If I make it past that, I do think it’d be fun to add in other planets!
