Terraforming Time Calculator

Updated: v2026.02.13

Estimate terraforming duration based on installation count, technology level, and target atmospheric change. Compare up to 2 configurations side-by-side. All tech values are verified against the Aurora game database (AuroraDB.db v2.7.1).

Note: Gas-specific modifiers vary by gas type but exact per-gas values are not fully database-verified. The default modifier of 1.0 is used; adjust manually if you know the modifier for your target gas. Effective rate also scales with planet radius — this calculator assumes Earth-sized bodies unless adjusted.

Omitted: Exact per-gas modifier values are not fully database-verified. Use 1.0 as default and adjust if known.
