How Do I Make A Procedural Planet?

I heard of this thing called a procedural planet which I heard is like when you go into the fog it transitions to a new level where you create the terrain from there.

Can anyone tell me how to do this or show me a video on how to do this?


You’re not going to get a video on this and nobody is going to show you.

You’re talking about highly specialised algorithms that takes people hundreds, if not thousands of hours to create.
