cratered planet 3d model

A photorealistic 3D planet sphere viewed from space. The surface is entirely barren — dark grey and brown rocky terrain, impact craters scattered across the surface, no water, no vegetation, no atmosphere. Surface texture resembles the Moon mixed with Mars. Color palette: dark charcoal grey #2a1a0a, rust brown patches, crater shadows in near-black. No clouds. No atmospheric glow at the edges. Black space background with no stars. The planet fills 80% of the frame, perfectly centered. Render style: photorealistic, physically based rendering, high detail surface texture, 4K texture maps. Export as GLB.
