With a surface temperature over 850 degrees Fahrenheit and an atmosphere thicker than ocean water, Venus is as close as we've ever come to discovering Hell. In order to tame this nightmare, your first priorities will be to thin the atmosphere, cool the planet, and clear the skies. Only then will you be able to gather water on the surface, and begin planting the first seeds of life.


Venus is a scorching world with a crushing atmosphere. You need to use facilities that lower the Pressure while still earning Credits. Only visit the World when you really need to until the Pressure is below 2,000,000 Pa, because if you aren't actively playing on the world, there will be no Random Events popping up.

Terraforming the planet is relatively easy. Temperature is only extreme because of the catastrophic pressure. Once you get the pressure down, Temperature will need just a little tweaking. The planet does not need much Water for human habitabillity (150,000 cm at minimum).


Do not use Hydrogen Processors because they will generate byproducts in a negative way. Consider using Biofixture Labs, which only generate Biomass (Oxygen in Biosphere). If you are playing Biosphere, set up a couple of Oxygen Filters.

Venus isn't playable right away, it requires that you achieve victory on Mars before being able to start a new game on Venus.

Areas that are blue and purple are below sea level, green, yellow, orange and red are above sea level.


  • Venus was the first world to be featured in a Live Event, Under Pressure.
  • Defining the rotation as retrograde, as done by NASA space missions and the USGS, puts Ishtar Terra in the northern hemisphere and makes the axial tilt 2.64°. Following the right-hand rule for prograde rotation puts Ishtar Terra in the southern hemisphere and makes the axial tilt 177.36°. - Wikipedia
  • The Daughters of Gaia originate here, as shown by the members' clan names hinting to various Venusian mountain regions.

  • In real life, NASA is not looking into terraforming Venus, but into building cloud cities in Venus' upper atmosphere, where the temperature and pressure are not as deadly as on the surface. They would basically be giant blimp cities, held up by the density of Venus' atmosphere. Native microbial life is also possible in this relatively habitable zone.
  • The real cause of Venus's extreme heat (which is also higher than the sun's closest planet Mercury (in daytime extremes)) is the runaway greenhouse effect caused by it's thick atmosphere, therefore the task of terraforming Venus' atmosphere and heat are closely related to those who look into terraforming Venus.
  • There is actually a time which Venus was habitable. From 4.45 Ga to 700 Ma, it had mild temperatures, an Earth-like atmosphere, liquid water, stable plate tectonics and possibly, multicellular life. But 700 million years ago, its oceans evaporated and carbon dioxide built up in the atmosphere, causing the runaway greenhouse effect.

  • One of the ideas of terraforming Venus is to send billions of genetically modified cyanobacteria into Venus' atmosphere. They will decrease the amount of carbon dioxide, and increase the amount of oxygen.
  • There is a hypothesis, that Mercury was the moon of Venus, but it cannot be true, because Mercury couldn't change the orbit by escaping Venus' velocity - when it left Venus' gravity, some huge body traveling in the opposite direction of Mercury must strike it to lower it's orbit.
  • Venus actually rotates retrograde in real life, reflected in-game by the inverted map of Venus.
  • Venus takes the longest to complete an axial rotation, about 247 earth days, longer than a Venusian year.
  • Venus had a moon before, but it collided back with Venus when a planet or swamp planet from space collided with Venus. It also caused its retrograde rotation.
  • In-game, Venus is 200 mK colder and 300,000 Pa less pressure than the real Venus.
  • Venus has poisonous clouds of sulfuric acid that extend 45 - 64 km above the surface.
  • Several landers had been landed onto the surface of Venus, but they melted quickly due to the extreme Temperature of its surface.
  • On the surface of the planet, the surface visibility is clear.
  • Venus overtakes Earth in its orbit for about 584 days.
  • Venus is the brightest object in the night sky besides Luna and the Sun. It is called the Morning Star when it rises before the sun and the Evening Star when it sets later than the sun.
  • Venus can be occasionally seen in the daytime sky. The other objects that cen be seen in daylight are Mars, Jupiter, The International Space Station, the Sun and the Moon or Luna.
