Stellar Zones
The habitable zone is the range of orbital distances where liquid water can exist on a rocky surface, determined by the star's luminosity and temperature.
The snow line marks the distance beyond which water ice and other volatiles condense. Gas giants tend to form beyond this boundary where icy material is abundant.
Inner rocky worlds form in the hot, volatile-poor region closer to the star. Their orbits remain stable as long as they don't enter orbital resonance with each other.
Body Classifications
Rocky I & II — Hot inner worlds, likely tidally locked
Terran — Within habitable zone, potential for life
Gas Giant — Beyond snow line, volatile-rich
Ice Giant — Outer system, icy composition
