Epsilon Eridani in fiction


The planetary systems of stars other than the Sun and the Solar System are a staple element in much science fiction. Epsilon Eridani is the fifth-brightest star in the riverine southern constellation of Eridanus. An orange star slightly smaller and less massive than the Sun, and relatively close to the Solar System, it is frequently featured in works of science fiction. It is classified as a type K2 star, with the corresponding suggestion that it has a stable habitable zone and is well suited for life. However, one factor which weakens the case for habitability is its youth—as little as 200 million years old—and consequent high levels of ultraviolet emission.

General uses

Many stars may be referred to in fictional works for their metaphorical or mythological associations, or else as bright points of light in the sky of the Earth, but not as locations in space or the centers of planetary systems.
The constellation Eridanus flows north and south in the night sky, and Epsilon Eridani is one of its more northerly stars, which allows it to be seen from most of the Earth's surface. However, because of its unprepossessing appearance in the sky, and its want of a "good" traditional name to supplement its esoteric Bayer designation, Epsilon Eridani has rarely if ever been used in a general sense, either in traditional mythologies or in the arts and literature that draw inspiration from them.
The star's popularity as a subject of science fiction stems not from its general cultural resonance, but from the astronomical data:
There follow references to Epsilon Eridani as a location in space or the center of a planetary system, categorized by genre.

Star Trek

Star Trek, a film, television, and print franchise originated by Gene Roddenberry. In some fictional reference works such as the Star Trek Spaceflight Chronology and the Star Fleet Technical Manual, Epsilon Eridani has been suggested as the possible star system of the planet Vulcan, the home planet of the Vulcan race, although James Blish had earlier proposed constellation associate 40 Eridani A as the Vulcan star system. The Star Trek canon later established Vulcan's distance as consistent with that of 40 Eridani, and the authorized Star Trek book Star Trek: Star Charts identifies it as such, while Epsilon Eridani was assigned a lesser role as the location of Axanar. The 40 Eridani location is furthermore attested by Roddenberry himself and in a statement by Commander Tucker in that "Vulcan is 16 light years from Earth"—as is 40 Eridani A at 16.39 ly from the Sun.

Babylon 5

Babylon 5, a space opera television series created by J. Michael Straczynski. This series, rife with prophecies, religious zealotry, racial tensions, social pressures and political rivalries, is centered on the eponymous Babylon 5 space station, a five-mile long O'Neill cylinder located in the Epsilon Eridani star system at the fifth Lagrangian point between the fictional planet Epsilon III and its moon. In this fictional universe, Epsilon III is the site of an ancient alien machine-city - known as the Great Machine - that is more than once instrumental to the plot of the show that revolves around galactic-level wars and politics.
