Earth

Earth, also known as "Terra" in Inspector #13, is the home planet of Humans, a few aliens, even some human and alien hybrids, including many animal life forms, located in the Solar System as the third planet. Earth is said to be a Level 2 planet and it appears as the common setting in many Role-Playing Sessions. An odd thing about the planet is that a great deal of alien activity happens on Earth which isn't a trans-galactic level civilization.
