A '''constellation''' is a group of stars that ancient [[astronomers]] imagined as pictures, so ordering the apparent chaos of the night skies. Not all the ancient constellations still exist, while some are comparatively modern. Their boundaries have become fixed over time: the present 88 constellations were defined by the [[IAU]] in 1925. The [[Latin]] names are the official ones.

A constellation is a formation of stars that ancient astronomers perceived as figures, like men or animals, so ordering the apparent chaos of the visible night sky.

Such figures are arbitrary, so numberous ancient constellations were independently imagined by different cultures, like the Chinese culture or the Indian culture.

The 88 modern constellations, which divide the whole night sky, were defined, as well as their boundaries, by the IAU in 1925. Most of them are ancient constellations in the Western culture, and they are officially named in Latin. The Latin declinaison of a constellation name in the genitive is conventionally used to build the designation of any star of the formation.

History of the Western constellations

Most constellations have their origins in the ancient Greek, Egyptian and Babylonian cultures. In the third century BC Aratos of Soli composed Phainomena, a didactic poem about the mythology of the constellations, which was the basis of the catalog of 48 constellations by the Greek astronomer Ptolemy. At the end of the 16th century the Dutch sailors Pieter Dirckszoon Keyser and Frederick de Houtman suggested twelve new constellations. In 1603 these were added by Johann Beyer to his important atlas Uranometria. Further constellations were added by the Gdansk astronomer Johann Hevelius and the French astronomer Louis de Lacaille. Lacaille introduced 14 new constellations that were named after scientific instruments and artist's tools.
