Exotic Terrestrials

Temperate worlds crusted in minerals no Earth rock knows.

An exotic terrestrial is a temperate, breathable-adjacent world whose crust skipped the silicate playbook: calcium carbonate plains, titanium-gray mesas, potassium salts - chemistry that builds a solid, weatherable surface without any of Earth's silicon and iron. They sit apart from earth-likes (no silicate continents, no iron core) yet can hold air, water, and high habitability scores. Build one by giving a temperate rocky recipe its minerals as calcium, titanium, or aluminum instead of silicon and iron.

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.
