{{version|2.23}}[[File:Trinary star system.png|thumb|320px|A trinary star system]]{{Celestialbodynav}}A '''celestial body''' is a named object (such as a star, planet , moon or large asteroid) occurring within present in a star system. Celestial bodies may have [[resources]] which can be harvested by [[Construction#Mining stations|orbital stations]]. Planets may also be habitable Each start system can have between 2 and capable to be colonized by empires with the right suitability or technology15 celestial bodies.
When any owned ship enters a system or passes within its sensor range, any habitable planets in the system will be revealed along with their world type. To see further details about the celestial bodies in a system, it is necessary to survey them with a science ship. This will reveal all of the orbital resources associated with each planet or asteroid. For habitable worlds this will also reveal more detailed world information including: size, surface tiles and their resourcesavailable districts, [[Planetary features#Blockers|blockers]] (if any), special features, and the habitability percentage for each species in the player's empire. Additionally, surveying worlds has a chance to reveal [[anomalies]].

=== Habitable worlds ===
{{hatnote|For the various specialized colony types, see [[Planetary_management#Designation|Planetary management § Designation]].}}
A habitable world is any celestial body that can harbor advanced organic life. These are the only worlds that can be [[colonization|colonized]] and [[Terraforming|terraformed]], besides some notable exceptions. Their suitability ranges in accordance to a given [[species]]' homeworld, which affects the rate of [[population]] growth.
A planet's habitability (and subsequent future terraforming costs) is determined by its climate system. The 9 nine habitable worlds are divided equally into 3 three climate categories: dry, frozen and wet.

== Habitability Celestial body modifiers =={{SVersion|2.2}}Habitability is the measure of how well a species can live on a planet. Every species has a climate preference for one of the primary habitable world types. A planet's habitability (and terraforming cost) is determined by its climate. The 9 habitable worlds are divided into 3 climate categories: dry, frozen and wet. Gaia worlds and Megastructures have maximum habitability for all species while Tomb Worlds and Machine Worlds are normally uninhabitable by biological species.{| class="wikitable"|-! Tier! Base |-|'''Gaia, Megastructures and Ecumenopolis'''| 100% |-|'''Exact Match'''| 80% |-|'''Climate Match'''| 60% |-|'''Climate Mismatch'''| 20% |-|'''Tomb World and Machine World'''| 0% |}Worlds of any type may have features which either increase or decrease their habitability. If present, these features will be identified when the world is surveyed by a science ship. === Habitability Effects ===* Every 1% of Habitability under 100% increases the Pop Upkeep and Amenity Usage by {{red|1%}} and their resource output and happiness by {{red|0.25%}}. It caps at 0% Habitability, giving {{red|+100%}} Pop Upkeep and Amenity Usage.* Homeworlds have a +30% habitability for the species originating on them.* Low Habitability can also trigger events. === Habitability strategy === ====Terraforming==== [[Terraforming]] allows the change of the Climate class to be one more suitable for the intended Colonists. However, the process There is very costly, requires decades of time and requires special technology if it is not only from a secondary to the primary habitability. This step can now be done retroactively on an already colonised planet, once the relevant tech has been researched. However, during Terraforming, Pops will suffer {{red|−20%}} to their {{iconify|happiness}}. ====Subspecies==== Using [[genetic modification]], one can create a [[Game Terms|subspecies]] of the empires primary species small chance that is suitable for the Climate in question. However, this needs either the first-in approach (so they can be changed on the new Planet) or a staging area with increased Habitability regardless of current Climate Preference (Ringworld, Habitat, Homeworld, rare modifiers). Changing a habitability trait now cost the equivalent of adding a trait worth 3 trait-points. The relevant tech must also be researched before the habitability trait can be changed. ====Xenos==== With all the possible habitability types, there are bound to be some aliens that can live comfortably on planets which are unsuitable to the primary species. The main disadvantage is that xeno pops have increased Unity cost per pop and might not have favorable traits. There may also be unwanted Xenophile attraction/Faction interactions from this path. Both via Conquest and Migration Treaties, one can add xeno pops to the Empire to use as colonists. If the empire is Xenophobe, the rights limitations for xenos will make the pops also considerably less happy. The migration approach requires a "first-in" colonist. Genetic Uplifting, Enlightenment and Infiltration can be used to acquire a xeno species as well. With the first one, it might even be possible to get a rare Habitability like {{iconify|Tomb}} Worlds. Very rare species native to Tomb Worlds are extremely adaptive and can thrive on any kind of planet (every normal class is secondary). The usual way of obtaining these species as subjects is finding them as upliftable semi-sentients on Tomb Worlds and uplifting. The event chain Horizon Signal can also create a subspecies of your main species with this trait. Alternatively, pops of your main species on Tomb Worlds may mutate and develop into their own species native to Tomb Worlds. ====Robots====All robots, including the primary species of {{iconify|Machine Intelligence}} empires, have 100% Habitability on every kind of inhabitable world. However, only drones and synthetics can actually be colonists. Synthetics are good to superior in all tasks, but also increase the Unity costs. Robot pops furthermore have a massive draw towards Materialist ethics, both for themselves and other pops on the planet. While the initial growth might be slower than a pure biological species, once the pop count is sufficient, Robots will also grow a lot quicker than biological species. Droids or synths make particularly good "first in" colonists, if they can be moved off or Materialist attraction is acceptable. === Visual cues ===Systems containing surveyed or non-surveyed habitable worlds celestial body will have one or more planet icons that are either green, yellow, orange, red, or blue, depending on the habitability percentage and/or status of the planet(s) in questionmodifiers. * [[File:Colonizability green.png|24px]] Green: The world is ≥70% habitable for at least one species in the player's empire.* [[File:Colonizability yellow.png|24px]] Yellow: The world is 40–69% habitable for at least one species in the player's empire.* [[File:Colonizability red.png|24px]] Red: The world is <40% habitable for all species in the player's empire.* [[File:Colonizability orange.png|24px]] Orange: The world is habitable but not surveyed.* [[File:Colonizability blue.png|24px]] Blue: The world is currently being [[Terraforming|Terraformed]]. Sometimes other factors can prevent colonization of a world. Some common reasons for not being able to colonize an otherwise habitable world are:* There is an anomaly on the world which has not yet been researched* The world is inhabited by a pre-FTL civilization Zooming in to the system and hovering over the planet icon may reveal useful information about what is preventing the player's empire from colonizing the world. e.g. If the tool tip says the world is 'controlled by Unidentified Empire' or 'belongs to someone else', another empire is in control of the system. In this case, surveying the world They will reveal the empire that controls it. This action can cause the player's science ship to be missing in action for up to a year, so it may be preferable to avoid surveying the world. Since different species can have different world type preferences, it can be better for an empire to populate its worlds with other alien species, genetically-engineered subspecies, found when surveyed or even robots/synthetics. It is also possible to [[Terraforming|terraform]] habitable worlds, though this is a costly through anomalies and time consuming process. Only planets of the main types (continental and such) can be terraformed, in addition to tomb and barren worlds with the "Terraforming Candidate" modifieraccompanying events== Planetary features =={{SVersion|2.2}}All planets have a random number of Planetary Features, which determine the number of Districts and Strategic Resource extraction buildings a world can support. Certain features are more likely to appear depending on the planet class.

Until a Blocker is cleared the obstructed Planetary Feature cannot be exploited. Each also reduces the maximum number of Districts on the planet by 1 or more, so they are worth clearing even if the extra possible districts are never built. Blockers can be cleared for a modest cost in minerals, energy, and time, if the player has researched the required technology. There are 9 such technologies, one for every normal blocker type, and they are all relatively easy to research. All normal blockers cost the same amount of resources to remove. Taking the [[File:Ap mastery of nature.png|21px]] Mastery of Nature ascension perk will reduce the cost of clearing blocks by 33%. {| class="mildtable plainlist"! width="1%" | !! width="12%" | Blocker! width="15%" | Spawn chance! width="11%" | Removal cost! width="25%" | Required removal tech! width="35%" | Description|-| [[File:d_active_volcano.png]] || Active Volcano|* x0.5 if [[File:Planet alpine.png|28px]] Alpine* x0.5 if {{iconify|Planet Size}} < 15* x0 if world is a moon| {{icon|enc}} 1000 {{icon|time}} 270| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Volcano Removal|21px}} Deep Crust Engineering| ''There is an active volcano in this region, spewing forth lava and volcanic gases.''|-| [[File:d_crater.png]] || Bomb Crater| * x0 if not [[File:Planet nuked.png|28px]] Tomb World| {{icon|enc}} 800 {{icon|time}} 270|| ''This massive crater was created Removed by the detonation of a particularly devastating hydrogen bomb.''|-| [[File:d_city_ruins.png]] || City Ruins| * x0 if not [[File:Planet nuked.png|28px]] Tomb World| {{icon|enc}} 1200 {{icon|time}} 360| | ''Once a great city, now just a metal boneyard stretching as far as the eye can see.''|-| [[File:d_dangerous_wildlife_blocker.png]] || Dangerous Wildlife|* x2 if [[File:PM Dangerous Wildlife.png|28px]] Hostile Fauna modifier* x10 if [[File:PM Titanic Life.png|28px]] Titanic Life modifier* x0.5 if {{iconify|Planet Size}} < 15* x0 if world is a moon| {{icon|enc}} 500 {{icon|time}} 270| [[File:TB Removal.png|Tile Block Removal|21px]] {{iconify|Dangerous Wildlife Removal|21px}}| ''The wildlife in this region is particularly lethal, with many dangerous predators and poisonous plants.''|-| [[File:d_deep_sinkhole.png]] || Deep Sinkhole|* x2 if [[File:Planet arid.png|28px]] Arid* x2 if [[File:Planet savannah.png|28px]] Savannah| {{icon|enc}} 500 {{icon|time}} 180| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Deep Sinkhole Removal|21px}} Subterranean Colonization| ''A colossal sinkhole covers most of this region.''|-| [[File:d_lush_jungle.png]] || Dense Jungle|* x2 if [[File:Planet tropical.png|28px]] Tropical* x2 if [[File:Planet continental.png|28px]] Continental| {{icon|enc}} 500 {{icon|time}} 180| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Dense Jungle Removal|21px}} Selective Defoliants| ''This entire region is completely overgrown with thick, impassable jungle.''|-| [[File:d_massive_glacier.png]] || Massive Glacier|* x2 if [[File:Planet alpine.png|28px]] Alpine* x2 if [[File:Planet arctic.png|28px]] Arctic| {{icon|enc}} 500 {{icon|time}} 180| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Massive Glacier Removal|21px}} Climate Control Network| ''An immense body of dense ice covers this region.''|-| [[File:d_mountain_range.png]] || Mountain Range|* x2 if [[File:Planet alpine.png|28px]] Alpine* x0.5 if {{iconify|Planet Size}} < 15* x0 if world is a moon| {{icon|enc}} 1000 {{icon|time}} 270| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Mountain Range Removal|21px}} Planetary Resurfacing| ''A vast range of tall and impassable mountains stretches across this region.''|-| [[File:d_noxious_swamp.png]] || Noxious Swamp|* x2 if [[File:Planet tundra.png|28px]] Tundra| {{icon|enc}} 500 {{icon|time}} 180| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Noxious Swamp Removal|21px}} Xeno-Hydraulic Mastery| ''Treacherous swamplands and bogs surrounded by putrid gases.''|-| [[File:d_quicksand_basin.png]] || Quicksand Basin|* x2 if [[File:Planet desert.png|28px]] Desert| {{icon|enc}} 500 {{icon|time}} 180| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Quicksand Basin Removal|21px}} Soil Remediation| ''A vast body of quicksand covers this region, making construction impossible.''|-| [[File:d_radioactive_wasteland.png]] || Radioactive Wasteland| * x0 if not [[File:Planet nuked.png|28px]] Tomb World| {{icon|enc}} 800 {{icon|time}} 270| | ''Few organisms can survive in this desolate, irradiated wasteland.''|-| [[File:d_toxic_kelp.png]] || Toxic Kelp|* x2 if [[File:Planet ocean.png|28px]] Ocean| {{icon|enc}} 500 {{icon|time}} 180| [[File:TB Removal.png|Tile Block Removal|21px]] {{icon|Toxic Kelp Removal|21px}} Ocean Ecology Management| ''A thick forest of kelp that is toxic to most forms of life covers the ocean in this region.''|-| [[File:d_gaseous_eruption.png]] || Rifts| [[File:Planet arid.png|28px]] Cracking| {{icon|enc}} 500 {{icon|time}} 120| | ''Seismological phenomena are causing the planet crust to crack, spewing out sulfuric gases and toxic slime.''|} ==== Homeworld blockers ====Two or three of each of these blockers are automatically generated on every empire's homeworld.
