How planets work
TerraForge is built on a physics model: the elements a world is made of, the star it orbits and how far away it sits decide what it becomes. These articles explain that model in plain language — what each rule is, where it comes from in real planetary science, and where we had to simplify.

How Does TerraForge's Habitability Score Work?
What the 0–100 habitability score measures: seven factors, why temperature and water limit the rest, the caps that override it, and its limits.
What Is the Habitable Zone, and Why Isn't It Enough?
What the Goldilocks zone is, why it moves with a star's brightness, where its edges come from, and why a planet inside it can still be lifeless.
How Do You Turn a Real Exoplanet Into a 3D World?
Which numbers NASA measured for each exoplanet, what TerraForge infers from them (composition, temperature, look), and where it has to assume.
Why Are Most Known Exoplanets Hot Giants?
Most known exoplanets are big and close to their stars because those are the easiest to detect. How transit and wobble surveys shape the catalogue.
What Decides a Moon's Surface? Ice, Haze, Volcanoes or Seas
How TerraForge decides whether a moon is icy, hazy, volcanic or temperate, and why moons recede, crash or become rings, with Io, Europa and Titan as guides.
