Luna is Earth's only natural sattelite and holds great importance in Terran history, notably for hosting the capital of the Solar Union. While Earth is traditionally more important in Solar politics, Luna was chosen due to the large areas of neutral ground available in close proximity to Earth, along with good access to space due to low gravity.
