Earth Sphere

The Earth sphere is a term seen throughout the Gundam metaseries, used to refer to different concepts and ideas that generally relate to one another.

There are almost always space colonies spread out around this region, some with relation to or are governed by Earth itself.

The term can also be used to refer to a governing body, in which Earth sphere refers to the Earth itself or the general concept of the location named the Earth sphere.
