Planets and moons reference

Use this table as a quick orientation layer. Difficulty is strategic, not moral judgment—hard destinations pay for preparation. Pair tips with the resource guide and launch windows pages when planning multi-year arcs.

Body Resources Difficulty Tips
Moon Helium-3 Easy Build fuel depot first
Titan Methane Hard Terraform priority target
Mars Water, Iron Medium Space elevator key
Venus CO2, Sulfur Hard Atmosphere processing chains
Ceres Water ice, Metals Medium Belt logistics hub

Extended planning note: match body choice to your standing fleet. Heavy chemical stages favor near-Earth and lunar cadence; electric or nuclear-electric options shift the calculus for outer moons and belt objects. Keep reserve budget for unexpected Δv taxes from plane changes or secondary objectives sponsors bolt on mid-contract.

FAQ

Which body is best for first expansion after the Moon?

Often Mars or Ceres depending on your contract mix—Mars for science and ISRU variety, Ceres for belt logistics. Colonization

Why is Titan marked hard?

Cryogenic operations, long comms delays, and harsh chemistry raise engineering and logistics thresholds.
