Browse 4,684 confirmed systems from the NASA Exoplanet Archive. Open one in 3D to inspect its orbits, compare it with our Solar System, and see how its planets were found.

Search more than 6,200 planets by host star or planet name, or filter for nearby stars, multi-planet systems, and planets in the habitable zone. Measured eccentricity is included when the archive provides it, so an elongated orbit appears that way in the model.


The discovery view explains transit, radial velocity, direct imaging, and microlensing with an animation based on the planet's published parameters. If the host star is above your horizon tonight, Space Time also tells you where to look.


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.
The catalog contains 4,684 confirmed systems and more than 6,200 planets from the NASA Exoplanet Archive. It is searchable and filterable.
Yes. Measured orbits with true eccentricities, driven by the same time controls as the Solar System.
The band around a star where liquid water could exist. It's shaded in each system, so you can see which planets fall inside.
Yes. "How we found it" explains transit, radial velocity, imaging, or microlensing with the planet's published parameters.
Yes. A one-tap overlay drops our orbits in at the same scale.
Often. If it's above your horizon tonight, Space Time tells you where to look and how bright it is.
