Sandbox

Stand in a world's own orbit. The selected body — planet or moon — is centred; drag to spin your viewpoint around it. A planet sees its star; a moon-world sees its host scaled by the angular diameter from the moon's orbit, with the sun a small distant disk. Tier: Galactic → System → World. All physics is shared with the System Generator, so the same seed yields the same worlds.

Body Focus

Sky bodies use real angular sizes — relative scale of host vs. sun is physical; the viewer's distance to the focal globe is a camera choice. Drag to spin · scroll to zoom · the full system lives on the System Generator.
System map · click any world to focus it above — a planet, a moon (the small dots above each planet, e.g. M-d.1), or the star. Shaded band = liquid-water window.
