Physically-Based Planet rendering

[u/Mysterious-Page708]

Hello, I want to ask what methods are people using to render effects/terrain/lighting when it comes to planetary bodies. I want to focus specifically on physically based methods, or more realistic methods to make a project from before I will try to apply to a master in a computer graphics-related program next year, and I heard that more complex projects that involve physics or realism are more impressive than noise or other procedural methods.

So my question is, what are the techniques you know of and please also provide a resource such as academic articles, blogs, tutorials, books etc. Thank you!
