Kepler-1652 b

Earth LikeHighly Habitable822 light years awayFound 2017

Kepler-1652 b, from the NASA Exoplanet Archive (found 2017). Measured: 3.19 Earth masses, 0.165 AU, a 3638 K M-type star. Composition inferred from a measured bulk density of 0.78x Earth's, which is rock and iron, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Life DetectedMagnetic FieldModerate Activity
Why is this a Earth Like?Your planet has a balanced composition with all CHNOPS elements, proper mass (3.2x Earth), and sits in the habitable zone at 0.17 AU.
Earth-like planets have the perfect combination of composition, temperature, mass, and magnetic field to potentially support complex life as we know it.
Classification Criteria:
✓ All CHNOPS elements present (C, H, N, O, P, S)✓ Mass: 3.2x Earth (0.5-2.0x range)✓ Temperature: 270K (250-320K range)✓ Magnetic field present✓ Distance: 0.17 AU (habitable zone)

The TerraForge exoplanet catalog: 5,572 real exoplanets run through the simulation, with a search field and rendered worlds grouped by type

New: The Exoplanet Catalog 🔭

Every confirmed planet NASA has measured well enough to build — 5,572 of them — is now in here, and none of them arrived with a label. Their real mass, radius, orbit and star go through the same simulation that runs everything you make, and it decides what each one is: gas giant, lava world, ocean, ice. Sixteen come out Earth-like. Find TRAPPIST-1e, stand on its surface, and see what a red dwarf's light actually looks like from the ground.
