Mitología de Centaurus

    Of the Greek Keutauroi, calls also Hipocentauros, were monstrous beings, mixture of man and horse. Generally, one imagines to them with six extremities, four legs of horse and two human arms, in other occasions, have human legs and still on seem men, from whose buttock later half of a horse arises. According to the legend, the Centaurs lived in the forests and mountains on the Élide, Arcadia and Tesalia, and happened through to be very robust and costumary brutales.

     Some of the centaurs have own personality and a particular treatment in the legend like Neso or Chiron, two figures that would be inexplicable if the Centaurs were fantastic monsters of the type of the Sirens or the Esfinges.  According to the legend Chiron, although he was inmortal, it did not want to survive the lacerantes pains that to him the wound produced that Hercules had inferred to him accidentally with one of his deadly arrows, What more appropriate dignity for the creator of the celestial sphere that the one to comprise of the eternity.

   But a legend referred by Píndado exists that gives to the Centaurs a divine genealogy, making them children of Centaur and mares the magnesias, although seems a this one secondary version of the myth; commonest it makes to the Centaurs children of Ixión and Néfele or of Apolo and Estilbe.

          It is a precious and enormous constellation that is located in the South hemisphere where it is the best place to observe it at great length. Where I write these lines to you, the constellation is observed partially, being visible the same North zone of, the less most interesting one from the point of view stellar although richer in observable galaxies, but visible in himself. Its partial zone I located the 2 to it of May of 1986. Logically I hope a day to be able to travel to the seas of the south and power to contemplate it in its splendor, the South zone of the richer constellation and in stellar and globular accumulations.

    It limits the north with the constellation of Hydra, already with its more western sector, to the east with Antlia and Candle, to the south with Crux, that practically is inside the constellation, with Musca and Circinus and to the west with Circinus and Lupus. Centaurus can be observed in austral skies during the months of February August and in the North hemisphere during May and June.

    Centaurus crosses the equator to him of the Milky Route by the South zone of the constellation, therefore it is in that zone where we can observe the prettiest accumulations and the most shining stars, among them the star alpha, the next to our single planet to 4.30 years denominated light Rigil Kentaurus.

 

Constelación de Centaurus

 

Main stars

         Alpha, a; denominated Rigil Kentaurus or of the Arab tolimán, that means eyetooth of the centaur, is the star next to our Solar System, is to 4.30 years light, that is to say, the light which we see in one night anyone is divided it from there recently more than four years. Its magnitude is practically of zero, 0.01 and of color like our Sun, yellow, it comprises of a double system with more than six thousand years of age, separated 17"of arc, and exists one third component, Proxima of name of magnitude 10.0 to a distance of 1º51 ' of the other two.

      Beta, b; call Agena and Hadar, its magnitude is of 0.60, is bluish and light is to 525 years. The association Scorpius Centaurus formed in a.

    Gamma, g; one is to the north of the constellation, of magnitude 2.18 white, is to 130 years Earth light. It is 180 times more luminous than our Sun formed in the accumulation of the Hyades, in Taurus.

 

Oher objects

             Omega, w; it then stars not a fine and enormous globular accumulation of magnitude 3.52, formed by stars of magnitude 11,0. Earth light is to 17,000 years. It has an angular diameter of more of 36'. One is in the central zone of the constellation.
