Planets provide players with resources and influence. Planets are on system tiles and each has a name, a resource value, and an influence value. Some planets also have traits.

  1. A planet’s resources are indicated by the value on its planet card and system tile that is surrounded by a yellow triangular border.
  2. A planet’s influence is indicated by the value on its planet card and system tile that is surrounded by a blue hexagonal border.
  3. A planet’s trait has no inherent effects, but some game effects refer to a planet’s trait. There are three traits: cultural, hazardous, and industrial.
  4. Some planets have a technology specialty, which allows those planets to be exhausted to satisfy a prerequisite when researching technology.
