The Earth is the planet in which most Marrissaverse characters reside, and in which the majority of all stories set in the Marrissaverse takes place. In many respects, it is presumed to be just like our Earth, except with its own unique citizens. In addition, a planet named "the Earth", presumed to be just like the Earth from real life, is usually the setting of a story not written for the Marrissaverse.

It has only one natural satellite, the Moon.

Generally, it is assumed that a story takes place on the Earth if at least one of its characters is both presumed to live there and is known to be associated with the Earth (e.g. someone lifted from real life or another work of fiction set on the Earth).
