Red Alien Planet orbiting a bright star.
Scene created in Blender and Rendered in Eevee. The planet surface was created with an 8k texture of the surface of mercury (included in the download) and then a detailed node setup (please see the reference image attached).
PLEASE NOTE: The fbx and GiTF will just be white plain spheres and the texture has not been baked into an atlas map. This scene is primarily for use within Blender, but with a little work it could be exported out and used in a game engine.
