This article is for the PC version of Stellaris only.
The planet interface serves as a key interface to the player as this is the place to construct civilian ships, recruit armies, and generally improve the planets under the player's control. This interface is accessed directly from the planet, from the outliner, through the expansion planner, etc.
Due to interface similarities the colonization tool is included in this article as well.
The planet summary screen provides an overview of the planet's important statistics. The extent of the information displayed depends greatly on whether the planet is colonized or not.
- Both instances
- Planet icon - Shows the planet type as well its habitability level (the value shown is the maximum among all empire species).
- Planet size - Determines the max amount of tiles on the planet. planet size also caps pops and buildings (one of each per tile).
- Uncolonized planets
All uncolonized planets provide basic summary details. Some options may not be available depending on the planet type.
- Terraform - Opens a list of planet types to terraform into with cost and time depending on climate choice. Terraforming alters the environmental conditions of a planet, to better suit a particular species.
- Colonize - Claim and populate the planet, provided it is in a controlled system. Upon clicking this the colonization tool will pop-up.
- Orbital tile deposit - Displays the resources that could be cultivated by a mining station.
- Colonized planets
- City image - Displays any special modifiers affecting the plant (usually discovered by surveys, but may also be applied from events).
- Resources - Lists all resources amounts available by the planet's tiles (only).
- Pops and Food production - The amount of pops on the planet. Pop growth time is affected by the empire wide amount of available surplus food. Note: Robots do not consume food or require it to grow (they must be manually built similar to buildings instead).
- Unrest - Caused primarily from unhappy pops. Applies penalties to production and may eventually lead to a full-blown revolt.
- Resource output - Lists all resources (except food) being generated on the planet. Note: The values are generally rounded to the nearest whole number; to see the actual value (and its break-down) hover over an icon.
- Governor - Displays the leader assigned to the planet's sector. The planet will be affected by the leader's traits.
- Edicts - Lists any planetary edicts currently in effect. These edicts are applied on a per planet basis (as opposed to empire-wide edicts). Available edicts are determined by technology, empire ethos, etc.
The surface tab serves as a visual representation of a planet's surface, divided into tiles. Each tile can support one pop and one building. This tab is only visible on colonies and surveyed worlds that are habitable.
- Resources - These appear below the tiles and can be only cultivated if there is a pop present on the tile. The generated value can be increased with the right building built on the tile. Note: Buildings will suppress any resources they do not generate.
- Tile blockers - These are obstacles preventing the tile from being worked by a pop or constructing a building. Most tile blockers can be removed eventually (indicated as ) for a cost, though some of them require a certain tech to do so.
- Adjacency bonus - The colony capital has adjacency effects; meaning, it provides a bonus resource production to any bordering tile (not diagonally) with a building that outputs the same resource.
- Pop indicators - Pops appear on the left half of the tile. They have a bar below them representing their happiness level. Growing pops will appear transparent and will sport a blue progress bar below them. Pop indicators can appear on the bottom left of the tile (slavery, unemployed, migrating).
- Building indicators - Buildings appear on the right half of the tile. Queued or currently constructed buildings will appear transparent and will sport a progress bar below them. Building indicators can appear on the bottom right of the tile (deactivated, no pop present) or on the top right (can be upgraded, upgrade not currently possible).
- Tile details
Upon selecting a tile on the planet surface the tile details screen will open next to it containing the following information (if present):
- Pop details - Lists pop traits, ethic and faction, happiness, consumer goods used and citizenship rights level. Players have the options of resettling the pop or changing its species rights.
- Building details - Displays the building and it's effects. Players have the options of temporary deactivating (for energy conservation), demolishing, replacing, or upgrading (if available) the building.
- Terrain details - Lists the base resource value generated by the tile itself. Tile blockers and their effects would be listed here before being cleared. This is the default section for empty tiles.
Armies and Starbase
The armies tab is used to manage all ground forces on the planet. Note: Enemy planets must (generally) be occupied by armies in order to claim them.
- Fleets - Indicate local fleets in orbit.
- General - Displays the highest-ranking leader assigned to the armies. The armies will be affected by the leader's traits.
- Planetary visualization - Provides basic visualization of armies on the surface or in the air (if embarked). Also displays a ground battle simulation.
- Embark/Land - Moves assault armies into orbit so they may be transported elsewhere, or brings orbiting armies down onto the planet.
- Orbital bombardment - Allows selection of bombardment stances (limited by policy) which determine the damaging effects of orbital bombardment. Bombardment can occur during the blockade of a planet by a hostile force.
- Combat width and Strength - Limits the number of armies involved in active combat per side, and displays the total strength of all armies defending the planet.
- Stationed armies - Lists all recruited armies currently stationed on the planet.
- Recruit - Opens a list of armies to recruit. The queued armies are listed above.
The spaceport's function is to construct new civilian ships to aid in the growth of the empire.
- Orbiting ships - Any ships currently in orbit will be listed here.
- Build - Opens a list of ship designs to construct. The queued ships are listed above. Note: While civilian ship classes may be built at any spaceport, military ships must be built at a Starbase with at least one Shipyard module present.
While it is possible to manually perform all the necessary steps needed to colonize a planet, the colonization tool smooths the experience by automating the process, leaving the player to make only the important decisions.
- The lists of empire planets provides a break-down of the species/sub-species (same species, but different ethic/traits) on each of them.
- The top right of the species description shows mineral cost of the colony ship and the species' habitability level for the planet in question.
- To colonize click on the flag icon at the top right of the desired species.
- Place the colony capital building on the planet's surface shown in the right half (planet modifiers are shown atop the tile visualization). Note: The capital building provides adjacency bonuses, so a central location would be of benefit in the long run.
