Altair in fiction


is a luminous white star in the constellation Aquila frequently featured in works of science fiction.

Star

Classified as an A-type main-sequence star, and located 16.7 light-years from Earth, Altair is one of the few stars for which a resolved image of measurable nonzero extent has been obtained. It rotates so rapidly, with a period of just 9 hours – compared to 25 days for the Sun – that it is significantly oblate, having an equatorial diameter more than 20 percent greater than its polar diameter. Among the authors of the fictional works in this article, not excluding Hal Clement, only Jerry Oltion has employed or even acknowledged the striking physical peculiarities of this star.
There is no evidence that the system is home to any extrasolar planets.
Altair is the brightest star in the constellation Aquila and the twelfth brightest star in the night sky. With an apparent visual magnitude of 0.77, it is one of the closest stars visible to the unaided eye. It forms a part of two well-known triplet asterisms: With β and γ Aquilae it forms the straight line of stars sometimes referred to as the Family of Aquila or the Shaft of Aquila; more prominently, it is the southernmost vertex of the Summer Triangle, the other two vertices being the bright stars Deneb and Vega.
The name Altair is from the Arabic, which translates literally as the flying eagle, from its belonging to the constellation. The star is named and plays a part in a variety of ancient myths worldwide, especially in the Western- and South-Pacific regions of the globe. In particular, in Chinese myth it is called the Cowherd Star after the story of the cowherd Niú Láng and his two children, who are separated from their mother Zhī Nŭ by the Milky Way. They are only permitted to meet once a year, when the Milky Way is crossed by a bridge of magpies.

General uses

Altair may be referred to in fictional works for its metaphorical or mythological associations, or else as a bright point of light in the sky of Earth, but not as a location in space or the center of a hypothetical planetary system:
