Salt Worlds

Blinding evaporite flats on dry, salt-crusted rocks.

A salt world forms when sodium and chlorine share a dry, warm rocky surface: with no water cycle to dissolve them, the salts precipitate into planet-wide evaporite flats - halite plains, brine pans, and salt-crusted ridges that gleam almost white under their sun. Build one by pairing sodium and chlorine on a dry rocky recipe inside the warm band, and keep hydrogen low so no ocean ever washes the flats away.

Surface views from three worlds: rocky ground under a ringed sky, a cloud deck, and a lit desert

New: Stand on Your World 🏔️

Every planet you build can now be seen from the ground. The terrain, the color of the sky, the weather and what hangs overhead are all read from the same numbers that shape the globe — so a thin-aired world gives you sunlit rock under a near-black sky crowded with stars, a runaway greenhouse seals you under an unbroken sulfur lid, and a gas giant leaves you in the cloud tops with nothing solid beneath you at all. If one of your moons wandered inside the Roche limit, what is left of it arcs overhead as rings.
