== Features ==
Planetary features represent notable areas on natural planets. They determine the number of resource Districts the planet can support and some features exclusively obtained by events can provide various bonuses to planets.

If a natural planet is terraformed into [[File:planet_city.png|24px|link=Celestial_body#Ecumenopolis]] Ecumenopolis, [[File:planet_infested.png|24px|link=Celestial_body#Hive]] Hive World, or [[File:planet_ai.png|24px|link=Celestial_body#Machine]] Machine World, it loses all of its planetary features, including event features. Hive Worlds and Machine Worlds do not lose the deposit features that determine the max number of Strategic Resource buildings.

=== Deposit features ===
These planetary features are generated on each natural planet and determine the number of resource Districts and Strategic Resource buildings the planet can support. If a planet is terraformed these features may be changed to new ones with the same effects that fit the planet class by flavor.

Dry planets are 50% more likely to have planetary features that increase the limit for Generator Districts or Mote Harvesting Traps. Wet planets are 50% more likely to have planetary features that increase the limit for Agriculture Districts or Gas Extraction Wells. Cold planets are 50% more likely to have planetary features that increase the limit for Mining Districts or Crystal Mines. Gaia planets are 50% more likely to have planetary features that increase the limit for Gas Extraction Wells, Mote Harvesting Traps and Crystal Mines.

== Blockers ==
{{SVersion|3.3}}
Blockers are obstacles that reduce {{iconify|District Cap}} by 1 (or more), and may block some planetary features from being exploited. They can be cleared by spending resources and time and some of them may have rewards when cleared. Clearing can be done while the planet is being colonized or after the colony is completed.

If a natural planet is terraformed into a planet class other than [[File:planet_city.png|24px|link=Celestial_body#Ecumenopolis]] Ecumenopolis, all of its blockers are cleared and rewards are given. If it was terraformed into [[File:planet_infested.png|24px|link=Celestial_body#Hive]] Hive World or [[File:planet_ai.png|24px|link=Celestial_body#Machine]] Machine World, the planetary feature it unblocks will be lost.

=== Natural blockers ===
These blockers can be found on natural habitable worlds and they unblock random planetary features when cleared. Most of them require a technology to be cleared.
