Planet

A world in orbit around the system centre. Planets are major economic bodies in any system. Their type determines what kind of colony world they are or whether they are a specialised orbital-only planet.

Purpose

Provide the foundation for conventional economic development. Planets have the highest sector slot counts of any stellar object type, making them the default location for building up extraction, processing, and logistics capacity.

Player Value

A planet gives a player room to build, extract, or specialise. The type of planet determines whether it can host a conventional colony, what kind of development is possible there, and what kind of resource profile it tends to carry. Most planets in the game world receive their own occurrence profile when they are created. Spawned homeworld planets are the exception and all use the same fixed profile.

Planet Types

Current planet types are all colony-capable worlds with distinct environmental identities.

  • Rock planets are solid rocky colony worlds and are commonly associated with Structural Materials extraction.
  • Desert planets are arid colony worlds with minimal moisture and harsh temperature swings.
  • Ocean planets are water-dominated colony worlds with deep global seas.
  • Continental planets are temperate colony worlds with mixed land and sea biomes.
  • Arctic planets are frozen colony worlds defined by ice, snow, and extreme cold.
  • Volcanic planets are hazardous colony worlds shaped by lava, ash, and active geology.

Resource Profile

Planets do not all share a single fixed resource role. Their occurrence profiles are assigned when the planet is created, and different planet types can support different economic identities.

Some planet types are more specialised than others.

  • Rock planets tend toward Structural Materials.

Most planets receive their own occurrence profile when the planet is created. Spawned homeworld planets all use the same fixed occurrence profile.

Rules

  • Planets orbit the system centre.
  • The current planet types are Rock, Desert, Ocean, Continental, Arctic, and Volcanic.
  • All current planet types are valid spawned homeworld types.
  • Each planet receives a resource occurrence profile when it is created. Spawned homeworld planets use one shared fixed profile. A planet's assigned profile does not change through gameplay.
  • Any planet can have moons in orbit around it.

Player Actions

  • View a planet's position within the system map.
  • View a planet's type, settlement role, and resource occurrence profile.
  • Claim a planet (subject to ownership rules).
  • Colonise a planet (subject to colonisation rules).
  • Place sectors on a planet (subject to infrastructure rules).

Constraints

  • Planets cannot be moved or destroyed by players.
  • Sector placement is governed by the planet's slot count. Slot count rules are defined in the infrastructure feature documentation.
  • Ownership and colonisation rules are defined in their respective features.
  • Extraction rules are defined in the extraction feature documentation.
