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 Lacerta as it can be seen by the naked eye. Lacerta is typical of Milky Way constellations: no bright galaxies, nor globular clusters, but instead open clusters, for example NGC 7243, the faint planetary nebula IC 5217 and quite a few double stars.

They are used to identify and locate constellations, stars, nebulae, galaxies, and planets. [1] They have been used for human navigation since time immemorial. [ 2 ] Note that a star chart differs from an astronomical catalog , which is a listing or tabulation of astronomical objects for a particular purpose.

Equirectangular plot of declination vs right ascension of the modern constellations with a dotted line denoting the ecliptic. Constellations are colour-coded by family and year established. Constellation families are collections of constellations sharing some defining characteristic, such as proximity on the celestial sphere , common historical ...
Each IAU constellation has an official three-letter abbreviation based on the genitive form of the constellation name. As the genitive is similar to the base name, the majority of the abbreviations are just the first three letters of the constellation name: Ori for Orion/Orionis, Ara for Ara/Arae, and Com for Coma Berenices/Comae Berenices.
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. For individual stars, see also the category Stars
