Epsilon Pegasi (ε Peg / ε Pegasi) is a star in the constellation Pegasus. It also has the traditional name Enif. In astronomy, an epoch is a moment in time for which celestial coordinates or orbital elements are specified. ... A Julian epoch is an epoch that is based on Julian years of exactly 365. ... Jump to: navigation, search This article is about the year 2000. ... Most stars are of nearly constant luminosity. ... In astronomy, stellar classification is a classification of stars based initially on photospheric temperature and its associated spectral characteristics, and subsequenly refined in terms of other characteristics. ... Right ascension (RA; symbol α: Greek letter alpha) is the astronomical term for one of the two coordinates of a point on the celestial sphere when using the equatorial coordinate system. ... In astronomy, declination (dec) is one of the two coordinates of the equatorial coordinate system, the other being either right ascension or hour angle. ... A light year, abbreviated ly, is the distance light travels in one year: roughly 9. ... Jump to: navigation, search The parsec (symbol pc) is a unit of length used in astronomy. ... The apparent magnitude (m) of a star, planet or other heavenly body is a measure of its apparent brightness; that is, the amount of light received from the object. ... In astronomy, the solar mass is a unit of mass used to express the mass of stars and larger objects such as galaxies. ... In astronomy, the solar radius is a unit of length used to express the size of stars and larger objects such as galaxies. ... In astronomy, absolute magnitude is the apparent magnitude, m, an object would have if it were at a standardized distance away. ... Jump to: navigation, search // In General Physics In general physics, luminosity (more properly called luminance) is the density of luminous intensity in a given direction. ... The solar luminosity is a unit of luminosity (power emitted in the form of photons) conventionally used by astronomers to give the luminosities of stars. ...

It is fairly average for an orange supergiant star, well into the later stages of its stellar evolution and as such may be considered a dying star. Enif likely only has a few million years left to go, although it is unknown whether it will explode in a supernova or simply die off as a white dwarf, due to its mass straddling the dividing line between stars destined to explode or not. Enif has been observed to brighten radically upon a few occasions, giving rise to the theory that it (and possibly other supergiants) erupt in mssive flares that dwarf those of our own Sun. A supergiant is a very large type of star which is ~10 to 50 solar masses on the Hertzsprung-Russell diagram. ... Jump to: navigation, search In astronomy, stellar evolution is the sequence of changes that a star undergoes during its lifetime, the millions or billions of years during which it emits light and heat. ... Jump to: navigation, search Remnant of Keplers Supernova, SN 1604. ... White dwarf Sirius-B in x-rays A white dwarf is an astronomical object which is produced when a low or medium mass star dies. ... A solar flare from NASA A solar flare is a violent explosion in the Suns atmosphere with an energy equivalent to tens of millions of hydrogen bombs. ... Jump to: navigation, search The Sun is the star at the centre of our Solar system. ...


The word Enif is derived from the Arabic word for nose, due to its position as the muzzle of Pegasus. Jump to: navigation, search Arabic (Arabic: العربية; transliterated: al-carabiyyah, less formally, عربي transliterated: carabī) is the largest member of the Semitic branch of the Afro-Asiatic language family (classification: South Central Semitic) and is closely related to Hebrew and Aramaic. ...
