A Planet is a type of environment that may host a colony. There are three basic types of planet: habitable, gas giant and dead. Habitable planets support colonies and can have specific traits. Gas giants and dead planets cannot support colonies but can generate as 
Promethion and 
Thulium deposits, respectively. They also block ship movement.

Planet traits are additional special bonuses a habitable planet may have.

Extreme worlds[ | ]
Some planets are theoretically habitable but have extreme conditions that generally prevent colonization. Colonizing a planet with an extreme trait requires a special technology or ability. Even if a world can be colonized, it will generally have a 50% penalty to 
Raw Production. More advanced technology or the right ability can negate that penalty or even provide bonuses. There are two tiers of extreme worlds with different unlocking patterns.
Tier 1 extreme worlds[ | ]
Colonizing the first tier generally requires the 
Extreme Colonization technology. A specific technology, depending on the trait, negates the penalty and adds minor bonuses. Every trait has a corresponding ability that enables colonization, converts the Raw Production penalty to a 10% bonus and adds major bonuses, which take precedence over the minor bonuses. The Xeno Adaptation technology and, except for corrosive and bacterial, the Adaptable ability have the same effect, except for enabling colonization.
Tier 2 extreme worlds[ | ]
Colonizing the second tier requires the Atmospheric Cleansing technology. A specific technology, depending on the trait, negates the penalty and adds minor bonuses. Every trait has a corresponding ability that converts the Raw Production penalty to a 10% bonus and adds major bonuses, which take precedence over the minor bonuses. The Ultimate Adaptability technology has the same effect.

Precursor worlds[ | ]
The Precursor Worlds DLC adds planets that are remnants of the precursor civilizations. Some of the precursor worlds suffer from extreme conditions, but most can be colonized immediately. All precursor worlds give intrinsic bonuses, with additional bonuses unlocked through technology. Colonizing a precursor world triggers a corresponding colonization event.
Normal precursor worlds[ | ]
Normal precursor worlds range in class from 11 to 20 and suffer from a penalty of -50% Food and -50% 
Synthetic Population Cap. By default, the worlds have +1 Raw Production and a bonus to ships produced by the planet. The 
Xeno Archeology technology instead gives +3 Raw Production and increases the ship bonus. The Precursor Exploitation technology further increases the ship bonus.

Extreme precursor worlds[ | ]
Extreme precursor worlds range in class from 18 to 22 and require Atmospheric Cleansing to colonize. By default, the extreme worlds have +5 Raw Production and another colony bonus. The Precursor Studies technology instead gives +3 Raw Production (bug?) and increases the colony bonus. The Precursor Engineering technology further increases the colony bonus.
