[a] Traditional astronomy tends to group stars into constellations or asterisms and give proper names to those, not to individual stars. 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').
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 ...
The German astronomer Johann Bayer created a series of star maps and applied Greek letters as designations to the stars in each constellation. Later a numbering system based on the star's right ascension was invented and added to John Flamsteed 's star catalogue in his book "Historia coelestis Britannica" (the 1712 edition), whereby this ...
As of 2008 The Stars: A New Way to See Them and a simplified presentation for children called Find the Constellations are still in print. A new edition of Find the Constellations was released in 2008, updated with modern fonts, the new status of Pluto, and some more current measurements of planetary sizes and orbital radii. [2]
Centred on a region of the sky without apparently bright stars, Lacerta was apparently not regarded as a constellation by ancient Western astronomers. Johannes Hevelius created the constellation in 1687 and initially named it "Stellio" (the stellion ), a lizard with star-like dorsal spots found along the Mediterranean coast.
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; List of Nakshatras – sectors along the Moon's ecliptic
The constellation Libra marked on a naked eye view. Overall, there are 83 stars within the constellation's borders brighter than or equal to apparent magnitude 6.5. [a] [2] The brightest stars in Libra form a quadrangle that distinguishes it for the unaided observer. Traditionally, Alpha and Beta Librae are considered to represent the scales ...
