The largest of five moons of Pluto, Charon is a very large moon in comparison to its parent body; it has half the diameter and one eighth the mass of Pluto, making it look almost more like a binary planetary system than a planet and moon.

In September 2016, astronomers announced that the reddish-brown cap of the north pole of Charon is composed of tholins, organic macromolecules that may be essential ingredients of life. This is one of many mysteries your explorers will be able to investigate upon arrival.


Charon is a moon of Pluto, another playable moon in TerraGenesis.


Charon is really small, so be sure to place your cities wisely, because you won't be able to place many. Just to be sure, place the first one within or below 10° of the equator, so you'll at least have somewhere to launch a Sky Farm satellite from. Also, build a socket city and start building the space elevator.

Because of Charon's small size, it is probably not wise to pick the UNSA or Horizon Corporation factions, because it will be hard to get enough cities to get to that large a population or revenue. Or maybe that is just the challenge you need. You could build a city dedicated to spaceports and coral reefs and other necessary buildings to achieve victory for the UNSA or Horizon Corp. Or, if your world uses Biomass, you can just spam Coral Reefs, as they earn both money and grow your population. They don't have any side effects, that after the world's habitability, so they are perfect for this job.


  • Charon was discovered in 1976.
  • Plantlife cannot survive on Charon, because it's very dark here, because it's very far from the sun.
  • Pluto can be sometimes be seen when playing Charon, but the Pluto is the current version of Pluto you saved.
  • Charon might have an ancient ocean in the past, probably due to tidal heating.
