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 [[Construction#Mining stations|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, [[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 nine habitable worlds are divided equally into three climate categories: dry, frozen and wet.

| 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.''
|- id="Desert"
| [[File:Planet desert.png|40px]] || 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.''
|- id="Savanna" id="Savannah"
| [[File:Planet savannah.png|40px]] || 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.''
|- id="Alpine"
| [[File:Planet alpine.png|40px]] || 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.''
|- id="Arctic"
| [[File:Planet arctic.png|40px]] || 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.''
|- id="Tundra"
| [[File:Planet tundra.png|40px]] || 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.''
|- id="Continental"
| [[File:Planet continental.png|40px]] || 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.''
|- id="Ocean"

| ''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.''

| The number of pre-generated Gaia worlds is limited.
* The home systems of three of the Fallen Empires contain Gaia worlds.
* 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.
* Empires with the {{iconify|Life-Seeded}} civic will start on a Size 25 Gaia world. Their species' climate preference will also be changed to {{iconify|Gaia}} World.
* A Gaia moon with a Stone Age pre-FTL civilization can be found if the Distant Stars DLC is installed.
* A Gaia world is located in the Sealed Wormhole system and requires defeating the Corrupted Avatar to claim the system.
* A Gaia world is located in the system housing the Tiyanki Matriarch and required defeating the guardian to be claimed.
* One of the outcomes of the Stellarite Devourer event chain will turn a frozen planet in its home system into a Gaia world.
* A system containing a size 25 Gaia world called Paridayda can be spawned as part of the Paradise Lost event. It has no natural resources but comes with a unique planet modifier granting various bonuses.
* A Gaia planet can be found in a special binary system. Every 3 months it changes between Gaia and Shrouded but claiming the system will allow the creation of a Special Project to permanently set the planet to a Gaia world.

=== Uninhabitable celestial bodies ===
All non-star celestial bodies that cannot harbor advanced organic life are classified as uninhabitable.  These worlds can't be colonized or terraformed, but can still be lucrative sources of common and strategic resources.

=== 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 [https://en.wikipedia.org/wiki/Stellar_classification 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.
