Terraformed Eris with statistics and cities

Originally considered to be a tenth planet because it appeared larger than Pluto, Eris is the most massive and second-largest dwarf planet known in the Solar System.

Its surface is a cracked and shattered mess, in keeping with it being named after the goddess of chaos and strife. It will be a difficult world to hominize, but then that's never stopped you before.


Eris is the second largest dwarf planet. The largest is Pluto. Eris has one large natural satellite - Dysnomia.

Eris actually does not have a hidden ocean of ice. This one is classified as hard because of strong erisquakes that even reach magnitude 15. So, heat up the planet, increase the pressure, increase oxygen, then water and biomass/terrestrial plant support, you get the point. It's very straight forward. Just make sure you leave enough room for enough cities.

Erisquakes happen often here because of the cracks, so do not place the cities on the cracks and the impact crater of Eris.


Almost terraformed Eris

Because Eris is very far from the Sun, it receives very little of the sun's heat and light. Even if we heat it, plant life cannot survive on Eris, because it's very dark here.

Eris's orbit is much more elliptical (0.44) than Pluto (0.25) but less than Ophadamia does (0.60). When it gets farther from the sun, it is 98× the distance from the sun to the earth (AU) and when it gets closer, it is about 38 AU. A year on Eris is about 559 years.

550 million years ago, a Dwarf planet about ⅓ the size of Eris collided, to form Dysnomia. A large impact Crater formed. At the opposite side of the impact, massive erisquakes crack open on the surface. That is why Eris has cracks ingame.
