mars planet 3d model

A photorealistic 3D planet sphere viewed from space. Pure dead Mars — dark rust-brown rocky surface, completely lifeless, no atmosphere whatsoever, large impact craters scattered across the surface, dark charcoal shadows in crater depths. Color palette: very dark rust #2a0800, near-black shadows, no color variation. No clouds, no atmosphere glow, no signs of life. Looks cold, dead and hostile. Black space background, planet fills 80% of frame, centered. Photorealistic, physically based rendering, 4K texture. GLB.
