Earth Sphere

In the Gundam anime metaseries, the Earth Sphere refers to Earth, the Moon, and all artificial satellites orbiting them. In light of the space colonization prevalent in Gundam, the term essentially encompasses humanity's expanded habitat.

Nearly all Gundam stories take place exclusively within the Earth Sphere, though a few involve events around Mars, Jupiter, and the asteroid belt.

Gundam SEEDs Cosmic Era takes place within the region of space which encompasses Earth,the Moon,and the orbiting space colonies. These colonies are located at areas of gravitational stability known as Lagrange points.

The area in the Cosmic Era shows the locations of the Lagrange points,the space settlements known as PLANTs, military bases, and a ring of orbiting space junk known as the Debris Belt.
