Alpha Centauri C is about 13,000 AU (0.21 ly; 1.9 × 10 ^ 12 km) from Alpha Centauri AB, equivalent to about 5% of the distance between Alpha Centauri AB and the Sun. [17] [57] [69] Until 2017, measurements of its small speed and its trajectory were of too little accuracy and duration in years to determine whether it is bound to Alpha Centauri ...
The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A , which is also the brightest star in Earth's night sky ; its white dwarf companion Sirius B is the hottest object among them.
The two bright stars are (left) Alpha Centauri and (right) Beta Centauri. The faint red star in the center of the red circle is Proxima Centauri. Centaurus in the Firmamentum Sobiescianum of Johannes Hevelius. N.B. This image is reversed from what one sees looking at the sky — it is as though one is looking at the "celestial sphere" from the ...
Such multiple star systems are indicated by parentheses showing the individual magnitudes of component stars bright enough to make a detectable contribution. For example, the binary star system Alpha Centauri has the total or combined magnitude of −0.27, while its two component stars have magnitudes of +0.01 and +1.33. [3]

In the film, Pandora is depicted as being located in the Alpha Centauri A system, 4.37 ly from Earth. It is one of the many natural satellites orbiting the gas giant Polyphemus, [3] named for the Polyphemus of Greek mythology.

This is the second nearest star system to the Sun, second only to the Alpha Centauri system. He was also a pioneering astrophotographer. His Barnard Catalogue lists a series of dark nebulae, known as Barnard objects, giving them numerical designations akin to the Messier catalog. They begin with Barnard 1 and end with Barnard 370.
