Known to early settlers as "The Walnut of Saturn", Iapetus is most recognizable for the tall ridge running most of the way around the moon along its equator, comprised of some of the tallest mountains in the entire solar system. Although at only 2% of Earth's gravity there isn't much need for a Space Elevator, such a prominent equatorial ridge would make for a perfect socket site if one were to be built.

We expect significant French immigration, as surface features of Iapetus are named after characters and places from the French epic poem, The Song of Roland. Though, given that Iapetus orbits almost three times farther out from Saturn even than Titan, immigration in general might be slower than usual.


Iapetus is the third largest moon of Saturn. The equatorial ridge can be seen and the marker for socket cities, making increasing revenue and population (especially if you are playing with UNSA) more efficient and quick.


There is a truly massive amount of water frozen in ice that you will need to get rid of as soon as possible if you want to terraform without flooding your planet.

The frozen in ice part of the Moons of Gas Giants is because real water or a subsurface ocean is impossible on TerraGenesis, so they made it Frozen in Ice.


What is interesting about this moon, it is two toned. On one side, it is white and the other side brown. It has an equatorial ridge.
