The Moon is the only natural satellite orbiting Earth. It orbits around Earth at an average distance of 384,399 kilometres (238,854 mi),a distance roughly 30 times the width of Earth, and completes an orbit (lunar month) in relation to Earth and the Sun (synodically) every 29.5 days. The Moon and Earth gravitationally pull on each other. The resulting tidal forces are the main drivers of Earth's tides, and have forced the Moon to face Earth with always the same near side, effectively synchronizing the Moon's rotation period (lunar day) to its orbital period (lunar month). This makes the Moon tidally locked to Earth.
Before the New Century, humanity first looked to the moon as a place to expand its population. Vast cities were constructed on the the Moon, expanding beneath its surface. Many of the largest corporations funded these cities, and nearly all of them relocated themselves to these moon cities once built. At the dawn of the New Century, it was decided that the EDA's capital would be Armstrong City, one of these cities on the moon.
Now, the Moon is the center for business and politics.
