Stellar bodies
Part of the Star systems guide
Stellar bodies are the planets, moons and other objects in a star system. Your buildings go on their tiles.
Body types
Each body is rolled within these ranges when the galaxy is created.
| Body | Tiles | Orbiting bodies | Industrial Potential | Scientific Potential | Appeal Potential |
|---|---|---|---|---|---|
| Habitable planet | 6–8 | 0–1 Moon | 1–5 | 1–5 | 1–5 |
| Barren planet | 6–8 | 0–1 Moon | 1–5 | 1–5 | 1–5 |
| Gas giant | 0 | 1–3 Moon | — | — | — |
| Asteroid belt | 0 | 1–4 Asteroid | — | — | — |
| Moon | 1–3 | — | 1–5 | 1–5 | 1–4 |
| Asteroid | 1–3 | — | 1–5 | 1–4 | 1–5 |
The infrastructure tile
Tile 1 of every planet is its infrastructure tile. Only an infrastructure building goes there. That is the Megapolis on a habitable planet and the Central Hub on a barren planet. A planet's other tiles need its infrastructure building first. See Infrastructure first. Moons and asteroids have no infrastructure tile.
Potentials
Every body with tiles has three potentials: Industrial Potential, Scientific Potential and Appeal Potential. Some buildings make more on a body with a high potential.
Buildings that scale with Industrial Potential
| Building | Built on | Effect |
|---|---|---|
| Industrial Hub | Habitable Planets | +3+60/h → +15+300/h Production per Industrial Potential; +6+120/h → +30+600/h Credit per Industrial Potential |
| Orbital Link | Habitable Planets | +8+160/h → +40+800/h Credit per Industrial Potential; +1.6 → +8 Mobility per Industrial Potential |
| Array of Excavators | Barren Planets | +2.8+56/h → +14+280/h Production per Industrial Potential |
| Metamaterials Factory | Barren Planets | +7+140/h → +40+800/h Production per Industrial Potential |
| Space Elevator | Barren Planets | +1.2+24/h → +6+120/h Production per Industrial Potential; +1.2 → +6 Mobility per Industrial Potential |
| Refining Ducts | Moons and Asteroids | +1+20/h → +3+60/h Production per Industrial Potential; +8+160/h → +20+400/h Credit per Industrial Potential |
| Swarm of Self-drilling Machines | Moons and Asteroids | +3+60/h → +15+300/h Production per Industrial Potential |

Star types
The star type sets how many bodies a system has, not counting moons and asteroids.
| Star type | Bodies |
|---|---|
| White dwarf | 4–6 |
| Red dwarf | 4–6 |
| Orange dwarf | 5–7 |
| Yellow dwarf | 6–8 |
| Red giant | 5–7 |
| Blue giant | 5–7 |
Some game modes change the body and star rolls. Outside a daily, your first system always has the same bodies, so it can fall outside these ranges. See Star systems.
