earth in fiction

Although nearly all fictional work features the Earth, this page describes its fictional place in the Universe.

It is common, in science fiction set far in the future, for Earth to fall into one of four categories:

Earth's location could have lost to the sands of time and with the planet presumed destroyed or rendered uninhabitable or even no one (human or otherwise) caring where it is. This scenario is expressed in the Foundation Series by Isaac Asimov, among others.
Earth's location could be unknown except for the few who live there, usually in some manner of utopia.
Earth could be a member of whatever interstellar community exists in the work, whether as a minor or major player. This is by far the most common option, and Earth (no doubt due to anthropocentrism) is usually a major power-broker.
Earth could have been completely destroyed or rendered uninhabitable, but its location (or at least its former location) is well-known. This last scenario is also popular, and was featured in the movie Titan A.E..

Hitchhiker's Guide

In the Hitchhiker's Guide to the Galaxy series by Douglas Adams, the Earth is destroyed to make room for an interstellar bypass. The only surviving Earthman, Arthur Dent, is affronted to find that his planet's entry in the Guide consists only of the single word "Harmless." The Guide researcher reassures him that the next edition will improve upon this. The new entry will read, "Mostly harmless." Dent also learns of the creation of Earth by inhabitants of the planet Magrathea, as a giant computer. It also mentions that humans are descended from a convoy of middlemen (bureaucrats, telephone sanitizers, and the like), tricked into leaving another planet. The Earth was located in sector ZZ9 Plural Z Alpha.

Star Trek

In the Star Trek universe, Earth was a founding member of the United Federation of Planets. Several major federal organizations are found on Earth, such as the Federation Council President's office (in Paris) and Starfleet Headquarters (in San Francisco). Major events on Earth included first contact with the Vulcans (), a barely averted attack by the Borg ("The Best of Both Worlds" (TNG)), and infiltration by the Founders ("Homefront" (DS9)). Like most other major Federation worlds, Earth is a near-paradise where poverty and war have been eradicated and environmental damage has been reversed.

Other fiction

The Earth also plays a major part in the Doctor Who universe and others. See also: Earth (Babylon 5).
