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.

Although these words are not strictly synonyms, they can be viewed as colours or connotations of a meaning or as a spectrum of a concept.
