Worlds in orbit

Famous planetary systems, drawn from above — every orbit to scale, with the habitable zone laid over the top so you can see which worlds fall inside it.

Orbit distances are to scale relative to each other and to the habitable zone — all in astronomical units (AU), so where a planet sits versus the green band is meaningful. Planet and star sizes are enlarged for visibility (planets are still sized relative to one another by radius). Orbits are drawn as circles; real orbits are ellipses. The habitable zone uses Kopparapu et al. (2014) — the conservative band is solid, the optimistic extension faint — the same model as our habitability tool. Data: NASA Exoplanet Archive.
