Real systems, true orbits
TRAPPIST-1, Kepler-90, Kepler-452, Kepler-186, Proxima Centauri, Tau Ceti. Step into any of them and watch the planets move on their measured orbits. The habitable zone is shaded, so which worlds sit in the liquid-water band is obvious at a glance.
Compare to our Solar System
One tap drops our Solar System's orbits in at the same scale. TRAPPIST-1 is a good one to try first: all seven of its planets orbit closer to their star than Mercury does to ours, and seeing both systems drawn together makes that real.
FAQ
Which exoplanet systems can I explore?
TRAPPIST-1, Kepler-90, Kepler-452, Kepler-186, Proxima Centauri and Tau Ceti, all with true orbits.
What's the habitable zone?
The band around a star where liquid water could exist. It's shaded in each system, so you can see which planets fall inside.
Can I compare to our Solar System?
Yes. A one-tap overlay drops our orbits in at the same scale.
Is it free?
Yes. In your browser, no account, no download.
