The (United) Federation of Planets is another name for the Association of Worlds, which is an extra-terrestrial organization that has been established for a number of purposes. See "Association of Worlds" for more information and links.
Please note that "Association of Worlds" and "Federation of Planets" are only two ways to denominate the same organization. Being an extra-terrestrial organization, the original name of the organization is of course not an English one. Both expressions are merely English translations of one and the same name, of one and the same organization.
Note that a lot of the information on the Federation is channeled, though corroborated by many contactees, and by some witnesses working on covert projects. Remote viewers, too, confirm the existence of such an organization.
