Kepler-1814 c

Lava WorldUninhabitable2367 light years awayFound 2023

Kepler-1814 c, from the NASA Exoplanet Archive (found 2023). Measured: 3.75 Earth masses, 0.0133 AU, a 4922 K K-type star. Composition inferred from a measured bulk density of 0.69x Earth's — too light for bare rock, so a large fraction of water and ice, with a day locked to its 0.6-day year, as anything orbiting this close would be.

Published by the NASA Exoplanet Archive. This world’s temperature and habitability score are computed from this star’s measured luminosity, not from a stand-in for its class.

Lava World

Magnetic FieldExtreme Activity
Why is this a Lava World?Your planet's proximity to its star (0.01 AU) results in extreme surface temperatures of 1802K.
Lava worlds orbit so close to their stars that rocky surfaces melt into oceans of molten rock. Recent planet formation can also create temporary lava worlds.
Classification Criteria:
✓ Temperature: 1802K (>1000K)

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.
