The moment that Neil Armstrong first stepped foot onto the surface of the Moon, our eventual colonization became inevitable. Decades would pass without us ever revisiting after those first few missions, but humanity has finally returned.

The Moon is much smaller than a planet, so you'll need to manage the space for your colonies wisely. But with luck, you'll turn humanity's first step into our next home.


The Moon is the only natural satellite of Earth and one of the playable worlds in TerraGenesis.

Terraforming this World is easy. The temperature can be ignored because it is at paradise levels, and the minimum habitable amount of Biomass is only 90,000 Mt.

The hard part is that you cannot place a lot of cities, which significantly slows the obtaining of Culture Points.


  • The Moon is the only satellite of a planet to be part of the first level pack, the free to play Terrestrial Planets. Earth is occasionally visible when playing on the Moon; this Earth's appearance is not default but is instead the most recent save of Earth you have played (if you have no Earth save, you will see the normal surface; Earth with it's default stats)
  • ).
  • The Moon is also available as a Natural Satellite when playing on Earth, with limited options.
  • On 20 July 2019, 25 free Genesis Points were given to players who played on that day to celebrate the 50th anniversary of the Apollo 11 manned Moon landing. This event was repeated on July 20 2021. The next one will be July 20, 2022.
    • The moon has practically no atmosphere, meaning there are no greenhouse gasses to regulate temperature. As such, the temperature on the bright side of the moon can reach 400 Kelvin and can drop to as low as 140 Kelvin on the dark side. The average temperature is -38.5 degrees Celsius or 235 kelvin.

d as Earth, about 4.5 billion years old than 4.55 billion as Earth does.

  • The prevailing hypothe
  • The prevailing hypothesis is that the Earth–Moon system formed after an impact of a Mercury-sized (or smaller) body (named Theia) with the proto-Earth (giant impact). The impact blasted material into Earth's orbit and became a ring of debris that clumped together to form a moon.
  • When the Moon was just formed it was much closer to Earth than now and even had a thin atmosphere - with a pressure of two atmospheres of Mars (1,200 Pa). The moon is going farther from Earth very slowly by about 4 cm/year. In about 2 billion years, it will be moving away faster than before (due to the sun's strong gravity) and will escape Earth's hill sphere and become a planet in the solar system, usually orbiting between Mercury and Mars.
  • The Moon difficulty in older versions was easy but then changed to medium.
  • The Moon is also called Luna by some people.
  • The Moon has a very, very thin atmosphere.
  • The game also does not reflect real-life abundances of the elements on different planets. For example, carbon is abundant for mining on the Moon in-game, but in real life only trace amounts of carbon exist on the Moon, much rarer than iron.
    • This may be due to the fact carbon was initially meant to be silicon, before Alexander mistook their concentrations. It has since then been kept, likely due to the low importance any correction would have.
    • Silicon is the second most common element in the lunar crust (after oxygen). Silicon on the moon is most commonly found in the form of the silicate ion, SiO4+4. Most lunar rocks are in the form of silicates.
