Is there a way to make multiple planets on Roblox?

I'm talking about the planets on the skybox, like the moon or the sun. I kinda need another planet besides those 2. Is there a way?

I am not exactly sure what you're asking for but I think your asking for worlds? You can do that by adding mutiple places to your game!

You cannot add another moon or sun. You can however remove them by the CelestialBodiesShown property.

The sky is actually fake - it's an illusion created by piecing together other images and is called a skybox. If you instead want to change that, look here
