I'm back and I've made market shares with the moon :
MoonSong: - powerfull late game civics options
None - default
Exploit requires industrial capitalism state ideology
gives +2 habitation (health) every city
+30% production
Protect
+1 happy for every 'craters' feature (forests) in city radius
the aliens will not attack you.
Terraform
Requires great project
Converts moon to earth-like terrain gradually
this greatly increases food production on the tiles
