Terraformed Sedna

Terraformed Sedna with stats and cities.

Orbiting at almost three times the distance of Neptune's orbit from the Sun, Sedna is quite large for its orbital neighborhood and easily recognizable as one of the reddest worlds in the outer Solar System.

With an orbit taking 11,400 years to complete, many scientists believe that Sedna was actually captured from a passing solar system by our Sun's gravity, or even that its orbit may be evidence for a large planet beyond the orbit of Neptune.

About[]

Sedna is a reddish dwarf planet that is much farther than Neptune, and it is extremely cold and has no atmosphere. It has no natural Satellites.


Sedna is the coldest world in TerraGenesis.

Strategy[]

Sedna is a very tiny planet, so make sure to keep the cities as close to each other as possible to leave room to place more. Firstly, use Ice Launchers to get rid of ice. Because Sedna starts with 0 Pa, there’s no need to increase the oxygen before the ice is gone. For the Temperature, it is highly recommended to use the Soletta, while increasing pressure to habitable levels with Spaceports. Then you can use water increasing facilities to increase the water level, but beware of flooding because Sedna is a small world! After that, can use Kelp Farms to increase oxygen while stabilizing pressure before you reach habitable oxygen. The biomass increase from the Kelp Farms should be enough for habitability. If not, you can wait for Natural Growth or use Coral Reefs.

Trivia[]

  • Sedna is the farthest planet from the Sun (if you count dwarf planets) in our solar system. It was found in November 14, 2003 by Michael Brown, David Rabinowitz, and Chad Trujillo. More information here.
  • Because Sedna is so far away, it receives a very small amount of the sun's light and heat. Even if we heat this world to habitable temperatures, it will still be nearly pitch-black all the time.

• Sedna's orbit is so eccentric that at aphelion (the point at which it is farthest from the sun), it will be about 900 AU from the Sun. This could be evidence of a planet 9, as no known bodies in the solar system could have exaggerated its orbit to the point at which it is today. If its path crosses Planet 9’s orbit, it might become a moon of it!
