A decent recreation of the solar system in Minecraft! I've tried my best to make it as close as possible. :)
Version: 1.14.4, or any version.

There is a viewing area that you will spawn in.

Make sure not to fall though!

Make sure to set the game mode to Adventure, in case you aren't already in it. I also did not include all of the moons because... 200 moons. Only the earth's moon.

Make sure if you have Optifine to turn off the Moon. Then there will be two moons!
