Planets

Planets are the foundation of your empire. Each planet provides building fields for construction and serves as a production center for resources.

Planet Properties

Property	Description
Fields	Building slots available (each building uses 1 field)
Temperature	Affects all resource production rates
Position	Location in the solar system (1-15)
Diameter	Visual size of the planet

Position Effects

Where your planet sits in the solar system determines its characteristics. Position affects planet size, temperature, and which resources you can produce most efficiently.

These are the exact production multipliers applied to base mine output at each position.

Temperature Effects

Temperature affects production for all three primary resources. Each resource has an optimal temperature zone:

Metal Mine Production

Metal production peaks in the temperate middle of the solar system and decreases toward both hot and cold extremes.

Temperature Zone	Multiplier	Best Positions
Middle (~+65°C)	2.0x	8, 9, 10
Warm (+110°C)	~1.7x	4, 5, 6
Hot (+260°C)	0.75x	1
Cold (-130°C)	0.75x	15

Metal thrives in balanced climates. Extreme temperatures—whether scorching or freezing—reduce extraction efficiency.

Crystal Mine Production

Crystal extraction improves dramatically on hotter planets near the sun.

Temperature Zone	Multiplier	Best Positions
Hottest (+260°C)	2.0x	1
Warm (+150°C)	~1.5x	3
Temperate (+65°C)	~1.4x	7, 8, 9
Coldest (-130°C)	0.75x	15

Crystal formations grow larger in high-temperature environments where geological activity is intense.

Deuterium Synthesizer Production

Deuterium collection is most efficient on cold, outer planets where the heavy hydrogen condenses more readily.

Temperature Zone	Multiplier	Best Positions
Coldest (-130°C)	2.0x	15
Cold (-50°C)	~1.6x	13, 14
Temperate (+65°C)	~1.4x	7, 8, 9
Hottest (+260°C)	0.75x	1

Deuterium extraction requires cold temperatures. Hot planets struggle to condense the heavy hydrogen efficiently.

Solar Satellite Energy

Hotter planets generate more energy per Solar Satellite:

Temperature	Energy per Satellite
+260°C (Position 1)	66 energy
+50°C (Position 6)	31 energy
-90°C (Position 15)	8 energy

On hot planets, Solar Satellites are extremely efficient. On cold planets, you'll need many more satellites for the same energy.

Strategic Positioning

For Your Main Base (Positions 7-9)

The middle positions offer the largest planets with excellent metal production. This is ideal for your homeworld or primary production planet.

Maximum fields for all your buildings (up to 327 fields)
Peak metal production at ~2x multiplier
Balanced crystal and deuterium production

For Crystal Production (Positions 1-3)

If you need crystal, the hot inner positions are best. The high temperatures dramatically boost crystal output.

Position 1 gives 2x crystal production
Trade-off: Lowest metal and deuterium production (0.75x)
Bonus: Solar Satellites are extremely efficient here

For Deuterium Production (Positions 13-15)

If you need deuterium, the outer positions are best. The colder temperatures maximize synthesizer output.

Position 15 gives 2x deuterium production
Trade-off: Lowest metal and crystal production (0.75x)
Trade-off: Solar Satellites are inefficient here

For Balanced Production (Positions 4-6, 10-12)

These positions offer good planet sizes with moderate bonuses across all resources.

Decent production of all three resources
Good compromise between specialization and flexibility

Colonization

Requirements

Astrophysics research (level determines max colonies)
Colony Ship (consumed on successful colonization)
Empty planet position (unoccupied coordinates)

Colony Slots

Your Astrophysics level determines how many colonies you can have (in addition to your homeworld):

Maximum Colonies = 3 + Astrophysics Level

Astrophysics	Max Colonies
0	3
1	4
2	5
3	6
4	7
5	8
...	...

Colonization Process

Build a Colony Ship at your Shipyard
Send it to empty coordinates with the Colonize mission
The ship is consumed and a new planet appears
Develop your new colony

Tip: Scout coordinates first to find the position you want. Don't just colonize randomly—position matters!

Your Homeworld

Your starting planet:

Given at account creation
Spawns at position 5 or 9 when available (fallbacks: 4, 6, 7, 8, 10, 11, 12)
Fixed size of 238 fields
Fixed temperature range of +20°C to +60°C
Cannot be abandoned

Abandoning Colonies

You can abandon any colony (except your homeworld):

Remove all stationed fleets first
Go to planet settings
Select abandon

Warning: All buildings and resources on the planet are permanently lost!

This frees up a colony slot for a new planet in a better position.

Quick Reference

Best Positions by Goal

Goal	Recommended Position	Why
Main base / Most buildings	7, 8, 9	Largest planets, best metal
Maximum crystal	1, 2, 3	2x crystal production
Maximum deuterium	15, 14, 13	2x deuterium production
Solar satellite efficiency	1, 2, 3	Hot = more energy per satellite
Balanced all-around	4, 5, 6, 10, 11, 12	Good size, moderate bonuses

Production Summary

Resource	Peak Position	Peak Multiplier	Worst Position	Worst Multiplier
Metal	8, 9	2.0x	1, 15	0.75x
Crystal	1	2.0x	15	0.75x
Deuterium	15	2.0x	1	0.75x

Your colony placement strategy should align with your resource priorities!
