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 ...

Constellations are groupings of stars as they are viewed, along a line-of-sight at a constant azimuth and elevation in the sky. This category identifies the 88 constellations currently recognised (areas of the sky) by the International Astronomical Union (IAU), plus some further subcategories.
