Orbital Atlas

How large are the worlds?

Enter a 3D lineup built from NASA equatorial diameters. Every globe shares one physical size scale, from the Sun at about 109 Earth-widths down to Mercury at 0.38. The gaps are compressed so the comparison remains explorable.

Navigate the observatory

Drag to orbit. Scroll or pinch to cross millions of kilometers. Right-drag or two-finger drag to pan. Select any world in space or from the target rail.
