The Tundra Planet
In brief:The Tundra Planet — cold planet in Xterium: temperature -225–-75 °C, up to 200–270 building fields, orbit 6–7. In the cold the Deuterium Synthesizer works more efficiently.

Profile
Orbit and temperature affect production: closer to the star — higher output from Solar Satellites, colder — the Deuterium Synthesizer works better. Fields are the maximum number of buildings on the planet.
Description and effect on production
A cold planet in orbits 6–7 (−225…−75°). The low temperature helps with deuterium extraction.
