Terminus is a fictional planet at the edge of the Galaxy in Isaac Asimov's Foundation Series, capital of the Foundation (later the Foundation Federation).
Terminus is the sole planet orbiting an isolated star. Its nearest inhabited neighbor is Anacreon, 8 parsecs (26 light years) away, and it lies approximately 10,000 parsecs from the capital of the First Galactic Empire, Trantor, near the galactic center. It is believed to be the planet farthest from the galactic centre, hence its name: Terminus is Latin for "end of the line". There are almost no visible stars in its sky, only the huge lens of the Milky Way Galaxy.
Terminus has a very high water/land ratio, with the capital, Terminus City, situated on the planet's only truly large island (not quite a continent). The planetary ocean contains a total of approximately 10,000 inhabited islands.
Terminus's climate is mild. Like all known habitable planets it has a nickel-iron core which produces a significant magnetic field; however, it has almost no metals in its surface rocks. In the Foundation's early years, steel was so valuable that it was used to coin money.
Prior to human occupation, a few, lower forms of life existed on Terminus. However, once humans arrived (along with their supporting species), these native life forms were crowded out and became extinct. Wikipedia
