# Fuel

**Fuel** is a necessary material to be able to go on expeditions to the Planets with your fleet, this must be acquired prior to the expedition. 

The cost of **fuel** will vary depending on the Planet you wish to explore, the farther away the Planet is, the **more fuel** will be needed by your fleet to go explore it, the approximate value of fuel is **10%** of the reward of that Planet.

All fuel costs are calculated with the Planet's base rewards, meaning, fuel cost will not increase as you level up.
