Centaurus is the ninth largest constellation in the sky, occupying an area of 1060 square degrees. It lies in the third quadrant of the southern hemisphere (SQ3) and can be seen at latitudes between +25° and -90°. The neighboring constellations are Antlia, Carina, Circinus, Crux, Hydra, Libra, Lupus, Musca, and Vela. Centaurus belongs to the Hercul...
The origins of Centaurus go way back to the constellation that the Babylonians knew as the Bison-man (MUL.GUD.ALIM). They depicted it either as a four-legged bison with the head of a man or a creature with a human head and torso attached to the rear legs of a bison or bull. The Babylonians associated the creature with the Sun god Utu (Shamash). In ...
Rigil Kentaurus – α Centauri
Alpha Centauri is a multiple star system, only 4.365 light years distant. It has an apparent magnitude of -0.27. Alpha Centauri A, the brightest component in the system, has a visual magnitude of -0.01 and is the fourth individual brightest star in the night sky, only slightly fainter than Arcturus in the constellation Boötes. The star system Alpha Centauri, however, is brighter than Arcturus. Alpha Centauri A, the primary star, is similar to the Sun: it is a yellow-white main sequence star b...
Proxima Centauri
There is a third star in the Alpha Centauri system. It is Proxima Centauri, a red dwarf that forms a visual double with Alpha Centauri AB and is believed to be gravitationally associated with Alpha Centauri AB. Designated Alpha Centauri C, it is separated by 2.2° from the binary star. It belongs to the spectral class M5Ve or M5Vie, which means that it is either a small main sequence star or a sub-dwarf. Its estimated mass is only 12.3% of a solar mass and the star is expected to remain on the...
Hadar
Beta Centauriis a blue-white giant star, 348.83 light years distant. It has an apparent magnitude of 0.6 and is the tenth brightest star in the sky. It belongs to the spectral class B1III. The star’s traditional name, Hadar, is derived from the Arabic word for “ground,” while Agena comes from the Latin word for “the knee.” Beta Centauri is a binary star, with the companion separated from the brighter component by 1.3 arc seconds. The brighter star, Hadar A, is a spectroscopic binary itself. H...
Centaurus A
Centaurus Ais the fifth brightest galaxy in the sky and one of the closest radio galaxies to the solar system. It is either a lenticular or giant elliptical galaxy, between 10 and 16 million light years distant. The galaxy has an apparent magnitude of 6.84. It is believed to contain a supermassive black hole at its centre. Centaurus A is thought to be undergoing collision with a spiral galaxy, which it is in the process of devouring. As a result, there is an intense burst of star formation in...
Omega Centauri (ω Centauri) – NGC 5139
Omega Centauri is a globular cluster in Centaurus. It is located about 4 degrees south of Centaurus A. The cluster has an apparent magnitude of 3.7 and is approximately 15,800 light years distant. It orbits the Milky Way Galaxy and is one of the largest, brightest globular clusters known that are associated with the Milky Way. The cluster is visible to the unaided eye. Originally listed as a star by Ptolemy, Omega Centauriwas later rediscovered by Edmond Halley who listed it as a nebula in 16...
NGC 4945
NGC 4945 is one of the brightest galaxies in the Centaurus A/M83 group and the second brightest galaxy in the Centaurus A subgroup. It was discovered by James Dunlop in 1826. The galaxy is approximately 11.7 million light years distant and has an apparent magnitude of 9.3. It is a spiral galaxy that contains an unusual, energetic Seyfert II nucleus, one that might contain a large black hole.
