The planetary systems of stars other than the Sun and its Solar System are a staple element in much science fiction. Vega (Alpha Lyrae) is a blue-white star in the constellation Lyra (the lyre, see High Sierra ) that is frequently featured in works of science fiction. Like its bright cousins Sirius, Deneb, and Altair, it is classified as a star of spectral type A. Roughly two and a half times the size of the sun, it is 40 times as luminous and, together with Arcturus and Sirius, one of the most radiant stars in the galactic neighborhood. Its luminosity joins with its relative proximity to the Earth—it is only 25 light-years away—to make it the fifth-brightest star in the night sky (see French and English Tragedy by George Croly). Vega is rendered decidedly oblate by its rapid rate of rotation [note 1] , and since it is pole-on to the sun, it appears significantly larger to earthbound observers than it actually is. For this and a variety of other reasons Vega has been extensively studied by astronomers, leading it to be termed "arguably the next most important star in the sky after the sun." [3]
Based on an observed excess emission of infrared radiation, Vega appears to have a circumstellar disk of dust. This dust is likely to be the result of massive collisions between objects in an orbiting debris belt, and it is analogous to the Kuiper belt in the solar system. [4] Irregularities in the disk also suggest the presence of at least one planet, about the size of Jupiter, in an orbit large enough to allow the formation of smaller rocky planets closer to the star. [5] Regardless of its ultimate tally of planetary companions, the fact that it has an estimated age of just 455 million years [2] suggests that the Vega system is too young to have fostered the development of life or a complex biosphere on any of its worlds.
The name Wega (later Vega) comes from a loose transliteration of the Arabic word wāqi‘ meaning "falling" or "landing," via the phrase an-nasr al-wāqi‘, "the falling eagle." [6] The star figures prominently in the mythology of cultures as diverse as the Polynesian, ancient Greek, Roman, Chinese (see Qi Xi ), Persian, and Hindu.
Vega may be referred to in fictional works for its metaphorical (meta) or mythological (myth) associations, or else as a bright point of light in the sky of the Earth, but not as a location in space or the center of a planetary system.
There follow references to Vega as a location in space or the center of a planetary system, categorized by genre:
Vega is referred to as a location in space or the center of a planetary system unusually often in fiction. For a list containing many stars and planetary systems that have a less extensive list of references, see Stars and planetary systems in fiction.
An ansible is a category of fictional devices or technology capable of near-instantaneous or faster-than-light communication. It can send and receive messages to and from a corresponding device over any distance or obstacle whatsoever with no delay, even between star systems. As a name for such a device, the word "ansible" first appeared in a 1966 novel by Ursula K. Le Guin. Since that time, the term has been broadly used in the works of numerous science fiction authors, across a variety of settings and continuities.
Planetary romance is a subgenre of science fiction in which the bulk of the action consists of adventures on one or more exotic alien planets, characterized by distinctive physical and cultural backgrounds. Some planetary romances take place against the background of a future culture where travel between worlds by spaceship is commonplace; others, particularly the earliest examples of the genre, do not, and invoke flying carpets, astral projection, or other methods of getting between planets. In either case, it is the planetside adventures which are the focus of the story, not the mode of travel.
The Two of Them is a feminist science fiction novel by Joanna Russ. It was first published in 1978 in the United States by Berkley Books and in Great Britain by The Women's Press in 1986. It was last reissued in 2005 by the Wesleyan University Press with a foreword by Sarah LeFanu.
The planetary systems of stars other than the Sun and the Solar System are a staple element in much science fiction. Sirius, a double star system with the binary designation Sirius AB, is the brightest stellar object in the night sky. Its component stars are Sirius A and Sirius B.
As one of the brightest stars in Earth's night sky, and the closest-known star system to the Sun, the Alpha Centauri system plays an important role in many fictional works of literature, popular culture, television, and film.
Tau Ceti is a star that hosts a planetary system and a common locale in much science fiction. It is the second closest spectral class G star to the Sun, making it a popular story setting or system of origin in science fiction tales. The Sun, itself of spectral class G, provides an obvious model for the possibility that the star might harbor worlds capable of supporting life. But Tau Ceti, weighing in at ~0.78 M☉, is metal-poor and so is thought to be unlikely to host rocky planets ; on the other hand, observations have detected more than ten times as much dust around the star than exists in the Solar System, a condition tending to enhance the probability of such bodies. Since the star's luminosity is barely 55% that of the Sun, those planets would need to circle it at the orbital radius of Venus in order to match the insolation received by the Earth.
Rigel is one of the brightest stars in the sky, usually the brightest star in the constellation Orion. It is frequently mentioned in works of fiction.
The planetary systems of stars other than the Sun, such as Betelgeuse, are a staple element in much science fiction.
Altair is a luminous white star in the constellation Aquila frequently featured in works of science fiction.
Aldebaran is a type K5 giant star in the constellation Taurus that is frequently featured in works of science fiction. Aldebaran is a subject for ancient myths in multiple cultures and, in more recent times, the mythologizing of science 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—it's as little as 200 million years old—and consequent high levels of ultraviolet emission.
Stars outside of our Solar System and their planets have been featured as settings in works of fiction since at least the 1854 novel Star ou Psi de Cassiopée by C. I. Defontenay, which depicts aliens living in the planetary system around Psi Cassiopeiae. A handful of works depict lifeforms not around but rather on or even inside of stars, such as the 1980 novel Dragon's Egg by Robert L. Forward and the 1993 novel Flux by Stephen Baxter, respectively; in both of these stories, the stars in question are neutron stars. Isaac Asimov's 1941 short story "Nightfall" portrays a planet in a multiple star system which is consequently in daylight from at least one of its suns for millennia at a time.

A significant number of science fiction works have explored the imaginative possibilities of binary or multiple star systems. Many real stars near the Sun belong in this category.
