The application maps them to 3D spheres, lights them, and applies fictional destruction effects; those effects are our modifications to their presentation. No endorsement is implied.

## Provenance and visual limitations

Solar System Scope identifies the collection as based on NASA imagery and elevation data. Its authors reference spacecraft photographs and telescope observations as color guides, while acknowledging saturated colors and invented terrain in unmapped regions. The source page does not document per-pixel lineage for each downloaded derivative, so these files should be credited to Solar System Scope rather than presented as unmodified NASA products.

Jupiter and Neptune maps depict clouds, not a solid surface. Any rigid pieces, impact damage, heat glow, or black-hole behavior shown in this sandbox is a fictional game effect, not a physical simulation. These textures represent the source authors' visual interpretation; in particular, saturated blue Neptune is not a calibrated natural-color reconstruction.
