I need a way to generate randomized planets that rotate slowly

I'm looking to create an nft minting website. The nfts I'm looking to create are going to be randomized planets that float over a small platform. The planets will have different land masses, weather patterns, colors, and other attributes. I've attached two photos just to give an idea of what im looking for. I've been told that a combination of blender and python sgould work for what im trying to accomplish.
