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, available 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]].

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.

{{SVersion|2.7}}

Special habitable worlds can only be spawned in certain systems but any empire that meets the requirements can terraform a regular habitable world into a special one. Some of them can become the empire homeworld if a certain origin is picked for the empire. All of them have either very high or zero Habitability and most of them feature fixed Habitability, meaning that Habitability cannot be reduced by effects such as traits.

This article has been verified for the current PC version (2.7) of the game.

A celestial body is a star, planet, moon or asteroid present in a star system. Celestial bodies may have resources which can be harvested by orbital stations. Each start system can have between 2 and 15 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, available districts, 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.

Planet size

The planet size determines the visual size of a planet and the maximum number of Districts the planet can support if it's habitable. Planets can have various sizes but habitable ones will always be within the following margins:

Type Min size Max size
Planet 12 25
Moon 10 15

Habitable worlds

A habitable world is any celestial body that can harbor advanced organic life. These are the only worlds that can be colonized and 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 nine habitable worlds are divided equally into three climate categories: dry, frozen and wet.

Type Climate Description
Planet arid.png Arid Dry Dry, rocky world with a nitrogen-oxygen atmosphere. The dust-covered terrain consists largely of mesas and canyons. Forests can be found in the more temperate polar regions, but vegetation is otherwise scarce.
Planet desert.png Desert Dry Dry, rocky world with a nitrogen-oxygen atmosphere. Precipitation and major bodies of surface water are relatively rare. Significant temperature variations between day and night cycles. Vegetation is scarce, but even moderate precipitation can make the desert bloom.
Planet savannah.png Savanna Dry Rocky world dominated by dry, arid plains covered by a nitrogen-oxygen atmosphere. The small hydrosphere allows for brief wet seasons, but aside from a few ubiquitous grasses vegetation is largely concentrated around shallow oases.
Planet alpine.png Alpine Frozen Mountainous world with a nitrogen-oxygen atmosphere. Snow covers the mountaintops and frozen-over lakes dot the valleys. While the planet experiences the minimal seasonal variations, the still-liquid water beneath the frozen surface of the lakes is enough to sustain some hardy vegetation.
Planet arctic.png Arctic Frozen Frigid, rocky world with a nitrogen-oxygen atmosphere. The poles are big, and significant water deposits can be found permanently frozen as glacial ice. However, the planet experiences seasonal variations and the equatorial band is covered by vegetation.
Planet tundra.png Tundra Frozen Cold and rocky world with a nitrogen-oxygen atmosphere. Permafrost covers most of the surface except for the more temperate equatorial regions. A stable biosphere exists but vegetation is mostly limited to mosses and lichens.
Planet continental.png Continental Wet Rocky world with a nitrogen-oxygen atmosphere. Active and stable hydrosphere. Great landmasses are separated by oceans, with large climate variations depending on latitude and precipitation.
Planet ocean.png Ocean Wet Rocky world with a nitrogen-oxygen atmosphere and a significant hydrosphere. Oceans cover more than 90% of the surface, with scattered islands making up the remaining percentage.
Planet tropical.png Tropical Wet Humid, rocky world with a thick nitrogen-oxygen atmosphere. Seasons with significant precipitation are interchanged with drier periods. Most landmasses are covered in dense vegetation.

Special habitable planets

Special habitable worlds can only be spawned in certain systems but any empire that meets the requirements can terraform a regular habitable world into a special one. Some of them can become the empire homeworld if a certain origin is picked for the empire. All of them have either very high or zero Habitability and most of them feature fixed Habitability, meaning that Habitability cannot be reduced by effects such as traits.

  • Gaia Worlds tend to have positive modifiers and no negative ones. Most DLCs add at least one system with a Gaia world but a few can be found in all versions:
  • A system called Wenkwart will always spawn in the galaxy. It contains size 19 Gaia world called Wankward Artem with a unique planet modifier.
  • A size 25 Gaia world called Zannam will occasionally spawn in a galaxy. It is defended by the Guardians of Zanaam.
  • Four Gaia worlds with special names - Prophets Retreat, Walled Garden, Emerald Mausoleum, Pristine Jewel - border the systems of the Holy Guardians. They have the Holy World modifier and colonizing them will incur their ire. Destroying them will even awaken the Fallen Empire.

Special uninhabitable planets

Special uninhabitable planets can only be created in unique systems or as a result of events.

Type Notes Description
Planet ai.png AI These planets are created by the Contingency. They are similar in appearance to Machine worlds, but are not habitable at all. Successful bombardment turns the planet into a broken world. Rocky world covered with artificial structures. The thin atmosphere consists mostly of industrial pollutants. There are strong energy emissions coming from across the entire surface, but no organic life signs.
Planet barren.png Cracked Created by the hatching of the Voidspawn, destroying the existing colony. Has a deposit of 20 Society Research Society. The cracked shards of an enormous planet-sized egg.
Planet infested.png Infested Created when habitable worlds are infested by the Prethoryn Swarm. Successful bombardment turns the planet into a barren world that can be terraformed. The surface of this world is covered by some kind of biological contaminant.
Planet toxic.png Nanite Found in the L-Cluster, with half of the outcomes giving them the Terraforming Candidate modifier once the nanite factory is destroyed. A chaotic and inhospitable world, disfigured according to some mad design.
Planet barren.png Shattered All worlds will have a deposit of 4-16 Minerals.png Minerals. The charred, broken remnants of what was once a planet. A massive energy surge has detonated this world's core, leaving only slabs of rock.
Planet arid.png Shielded Found through exploration, where the shield can be brought down through a special project with different possible outcomes. They can also be created using the Global Pacifier Colossus weapon but these worlds cannot then be un-shielded. This entire world is encased in some kind of impenetrable energy barrier. It blocks all scans of the surface.
Planet shroud.png Shrouded Created by the End of the Cycle or when the Eater of Worlds is ravenous. Cannot be recovered. A few shrouded worlds can be found in some special systems. Our sensors are unable to penetrate the thick fog surrounding the planet. Ships that enter it do not return.

Habitable Megastructures

Habitable Megastructures are entirely artificial and can be constructed after researching the required technology. They feature the same Mod habitability.png habitability for every species, have unique Districts and Designations and have no colonization cost.

Type Required technology Notes Description
Planet habitat.png Habitat Tech habitat.png Orbital Habitats
  • Mod habitability.png 70% Base Habitability
  • Has 3 types of Districts, with a fourth one being available if build over a planet with a resource deposit
  • Colonization is 3 times as fast as a planet
  • Starts at size 4 and can be increased up to size 8 with the required technologies
An artificial deep-space arcology offering planet-like, if decidedly urban, living conditions. Hydroponics and advanced filtering technologies make it near-self-sustaining, and station-borne facilities can mine the station's host planet for raw materials.
Planet ringworld.png Ring World Tech ring world.png Ring World
  • Mod habitability.png 100% Fixed Habitability
  • Housing.png +20 Base Housing
  • Intact Ring Worlds are found only in the the Sanctuary system and the Ancient Caretakers home system
  • The Shattered Ring Shattered Ring origin homeworld contains a partially damaged Ring World
  • Can be repaired from broken segments with the Tech mega engineering.png Mega-Engineering technology
  • Can be built in uninhabited systems
  • Segments destroyed by a crisis or World Cracker cannot be repaired
An immense band encircling the system's sun. Built to allow for numerous artificial habitation zones along its inner span, freed from the restrictions and mundanity of planet-bound, spherical existence.

Stars

A star is a celestial body that composes the center of a star system and influences the generation of the solar system. They are classified based on their spectral characteristics. Less common stars also have a negative effect on all ships in the system, making certain tactics less effective in battle.

Most systems have only one star but a few have two or three stars, either orbiting each other with the planets around them or far enough from each other that a few planets orbit each star. The effects and chances for habitable planets stack in binary and trinary systems.

B Star.png Class B
  • Energy Credits.png Energy
  • Physics Research Physics
-40% The large class B main-sequence stars are very bright and blue. Although somewhat rare, the luminosity of these stars make them among the most visible to the naked eye.
A Star.png Class A
  • Energy Credits.png Energy
  • Physics Research Physics
-40% These relatively young white or bluish-white main-sequence stars are typically among the most visible to the naked eye. They are large and rotate very quickly, but will eventually evolve into slower and cooler red giants.
F Star.png Class F
  • Energy Credits.png Energy
  • Physics Research Physics
F-type stars are fairly large and often referred to as yellow-white dwarves. Although they often emit significant amounts of UV radiation, their wide habitable zones have a good chance of supporting life-bearing worlds.
G Star.png Class G
  • Energy Credits.png Energy
  • Physics Research Physics
Often referred to as yellow dwarves, G-type stars actually range in color from white to slightly yellow. Main-sequence stars fuse hydrogen for roughly 10 billion years before they expand and become red giants. Although their lifespans are shorter than K-type stars, worlds inside the habitable zone of a G star often enjoy optimal conditions for the development of life.
K Star.png Class K
  • Energy Credits.png Energy
  • Physics Research Physics
These main-sequence stars, sometimes referred to as orange dwarves, are a fairly common sight. They are stable on the main-sequence for up to 30 billion years, meaning that worlds orbiting a K-type star have a longer than average window to evolve life.
M Star.png Class M
  • Energy Credits.png Energy
  • Physics Research Physics
-60% The most common stars in the universe, often referred to as red dwarves. Their low luminosity means they are difficult to observe with the naked eye from afar. Although they typically have an extremely long lifespan, red dwarves emit almost no UV light resulting in unfavorable conditions for most forms of life.
M Red Giant Star.png Class M Red Giant
  • Energy Credits.png Energy
  • Physics Research Physics
-90% With a large radius and comparatively low surface temperature, red giants are stars of moderate mass in a late stage of stellar evolution. Their expanded stellar atmosphere and high luminosity make for distant habitable zone orbits.
T Star.png Class T Brown Dwarf
  • Energy Credits.png Energy
  • Physics Research Physics
-60% Brown dwarfs are substellar objects that lack the mass to sustain hydrogen fusion. Roughly the size of large gas giants, they have a much greater density. Their low luminosity and comparatively small heat generation means that planets orbiting them are unlikely to support life.
Pulsar.png Pulsar
  • Engineering Research Engineering
  • Physics Research Physics
-100% Pulsars are highly magnetized neutron stars that emit beams of electromagnetic radiation. As the star rotates, the radiation beam is only visible when it is pointing directly at the observer. This results in a very precise interval of pulses, which sometimes is so exact that it can be used to measure the passage of time with extreme accuracy. The radiation emitted by pulsars interferes with deflector technology, rendering ship and station shields inoperable.

-100% Typically formed as a result of the collapse of a very massive star at the end of its life cycle, black holes have extremely strong gravity fields that prevent anything - including light - from escaping once the event horizon has been crossed. The gravitational waves emitted by black holes interfere with FTL drives, making it harder for ships to escape from combat.

  • Engineering Research Engineering
  • Physics Research Physics
-100% These incredibly dense stellar remnants are sometimes created when a massive star suffers a rapid collapse and explodes in a supernova. Although their diameter is typically as little as ten kilometers, their mass is many times greater than an average G-type star. The gravitational waves and radiation emitted by Neutron Stars must be carefully navigated around, slowing the sublight speed of ships.
