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 ...
A celestial map by the Dutch cartographer Frederik de Wit, 1670. A star chart is a celestial map of the night sky with astronomical objects laid out on a grid system. 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]
The Milky Way as seen from Earth, with prominent dark features labeled in white, as well as prominent star clouds labeled in black. The Great Rift, a series of dark patches in the Milky Way, is most visible in the southern sky. [66] Some cultures have discerned shapes in these patches.

The primary and secondary are both blue-white hued stars of magnitude 2.9; their period is 84 years. [2] Centaurus also has many dimmer double stars and binary stars. 3 Centauri is a double star with a blue-white hued primary of magnitude 4.5 and a secondary of magnitude 6.0. The primary is 344 light-years away.
The constellations along the ecliptic are called the zodiac. When explorers mapped the stars of the southern skies, European astronomers proposed new constellations for that region, as well as ones to fill gaps between the traditional constellations. Because of their Roman and European origins, every constellation has a Latin name.
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
Within the constellation's borders, there are 49 stars brighter than or equal to apparent magnitude 6.5. [e] [13] At apparent magnitude 3.3, Alpha Pictoris is the brightest star in the constellation; it is an astrometric binary 97 light-years from Earth.
