All stars but one can be associated with an IAU (International Astronomical Union) constellation. IAU constellations are areas of the sky. Although there are only 88 IAU constellations, the sky is actually divided into 89 irregularly shaped boxes as the constellation Serpens is split into two separate sections, Serpens Caput (the snake's head) to the west and Serpens Cauda (the snake's tail ...
Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of Arabic فخذ الدب ( fakhdh ad-dubb, 'thigh of the bear'). Only a handful of the brightest stars have individual proper names not depending on their asterism; so Sirius ('the scorcher'), Antares ('rival of Ares ', i.e ...
Some stars in entirely different constellations had the same name: Algenib in Perseus and Algenib in Pegasus; Gienah in Cygnus and Gienah in Corvus, Alnair in Grus and Alnair in Centaurus. In 2016, the IAU organized a Working Group on Star Names (WGSN) [4] to catalog and standardize proper names for stars.
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. [ 1] The first constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, mythology.
The following lists of constellations are available: IAU designated constellations – a list of the current, or "modern", constellations. Former constellations – a list of former constellations. Chinese constellations – traditional Chinese astronomy constellations.
IAU designated constellations in equirectangular projection (epoch B1875.0) In contemporary astronomy, 88 constellations are recognized by the International Astronomical Union (IAU). [ 1] Each constellation is a region of the sky bordered by arcs of right ascension and declination, together covering the entire celestial sphere.
M5e-M6e. a variable star in the constellation of Andromeda. It is classified as a semiregular variable pulsating giant star, and varies from an apparent visual magnitude of 14.5 at minimum brightness to a magnitude of 9.9 at maximum brightness, with a period of approximately 238.3 days.
