Planets are an important part of Sins of a Solar Empire.

Allegiance
Allegiance is a percentage measure of how loyal your colonies are to you. It is individual for each colony.
Effects of Allegiance
Allegiance directly affects the income rates of planets. At an allegiance of 70%, credit, metal, and crystal income rates are cut to 70%. Low allegiance can tremendously affect your economy, so it is wise to pay attention to it. If it drops to 0%, your colony will revolt and be lost.
Maximum Allegiance
The maximum allegiance for a planet is based on its distance to your homeworld, as shown in the table below. The base value, however, starts out 10% below the maximum.
| Distance | Base Value | Maximum |
|---|---|---|
| 0 | 100% | 110% |
| 1 | 90% | 100% |
| 2 | 80% | 90% |
| 3 | 70% | 80% |
| 4 | 55% | 65% |
| 5 | 40% | 50% |
| 6+ | 25% | 35% |
Affecting Allegiance
Allegiance is affected by culture. If friendly culture (yours or an ally's) is dominant at a planet, the allegiance will increase up to its maximum. If enemy culture is, it will decrease down to 0.
Analysis
Constructing Culture Centers (Broadcast Centers, Media Hubs, and Temples of Communion) at the edge of your empire near an enemy will spread your culture into his empire, decreasing his allegiance and crippling his economy.
Constructing Culture Centers within your empire will increase your allegiance by 10% up to the maximum, granting you 10% increased income, as well as making it more difficult for your enemies to sabotage it. This can definitely be worth it.
If your capital is to one side of your empire (common because homeworlds are usually at one edge of the system), it may be wise to move it near the center, so that the overall allegiance is increased. Compare these situations:
110 100 90 80 65
X-------O-------O-------O------O Sum=445
90 100 110 100 90
O-------O-------X-------O------O Sum=490
In the second, your allegiance has increased 45%, which represents a 10% increase in your overall income. That quickly pays for the expense of moving your capital.
