Suns

Suns are special objectives marked with a dashed circle for their radius.

Taking a sun

Suns are captured with super-probes. Drag from one of your planets to a sun and choose how many probes to send. On arrival every 100 probes becomes 1 super-probe and any leftover is lost, so an attack needs at least 100 probes. The super-probes fight the sun's defenders; finish with more than the defender and the sun is yours, along with its energy income.

Defending

A sun's super-probes come only from combat, since suns do not produce any on their own. Reinforce a sun you own by sending it more super-probes. Every attack wears its garrison down, so a contested sun changes hands through repeated assaults.

Sun swarms

You can also relay super-probes from one sun you own to another. They behave like normal swarms: all probes arrive (no loss), speed depends on where the source sun sits in its galaxy, and they fight on arrival. Drag from a sun you own to another sun to launch.
