Now this is the type of question I love! Hi! I am a game developer/programmer and to respond this question is simple. Yes, you can make planets, heck even other galaxies! This is going to be difficult though. Since every planet must be sphere and they are created in unity3d game engine. The first step is getting a 3d modeling program such as blender. In blender you must create a sphere and re size it to a specified size. Step 2 is to do whatever with the planet! Create mountains, Ice Caps, Cities, but not oceans! You make oceans in the game engine itself. Step 3, apply a texture to all land. Step 4, Bring into Unity3d and apply a ocean if you want. Step 5, Apply a script to make the planet spin and rotation to the sun. Step 6, Test the mod for bugs or errors. Right pretty straight forward although I have know idea how to 3d model things!
