>>10162654The structural layers of these bodies may not be ideal. Both are likely still cryogenically active and this places additional engineering strains upon a ring you could build around the equator.
The structure is essentially a thin eggshell consisting primarily of hydrated and mineralised clays atop a thin layer of ice.
Below this is an ocean of water containing ammonia and other liquids with antifreeze properties. This is the source of the cryogenic eruptions and fracturing of the surface.
Finally there is a rocky layer surrounding a dense and still warm core.
So the science thusfar theorises.
It's a problem. However not insurmountable.
