🛰️ The basic calculation chain

For each country, your planning system could calculate:

Country → Population → Planet → Gravity → Atmosphere → Water → Energy → Food → Resources → Infrastructure → Economy → Governance → Sustainability

And for every candidate world, use a 0–100 suitability score:

Suitability = gravity + atmosphere + water + temperature + radiation + resources + energy + accessibility + settlement capacity + long-term stability

One important correction to the concept: countries cannot realistically be assigned ownership of existing planets under current international space law. For a scientifically credible SpaceTrain proposal, describe them as internationally coordinated settlements, habitats, or cultural/economic zones, rather than sovereign ownership of celestial bodies.
