The constellation is best observed at latitudes from 26 ° north and 90 ° south. It is clearly visible in the first half of spring, namely in March and April. By its size, this constellation occupies about 1060 square degrees and is in the ninth place.

This cluster of stars in the night sky includesitself 389 objects. All of them can be considered without using any optics. Next to the Centaurus are other constellations such as the Wolf, Ship, Hydra, Southern Cross. By the way, even before the XVII century, the Southern Cross was not an independent element of the starry sky, but was a member of the constellation Centaurus.

The most famous objects of Centaurus

Alpha Centauri, or Rigel Centaurus, is one of thethe brightest stars that enter the constellation. It has 0.7 magnitude and is a whole system consisting of a double star - Alpha and Beta, as well as a red dwarf called Proxima Centauri. In what constellation is there still such a bright star system, moreover, located so close to our planet? From Proxima to the Earth is no more than 4.4 light years. It's not for nothing that "proximity" is translated as "nearest".

By the way, with these stars among wild peoples,who once lived in the southern hemisphere, was associated with a large number of different legends and legends. And Alpha Centauri in its spectrum, as well as the specific mass is very similar to the Sun. Moreover, an Earth-like planet is turning around the star.

Briefly about the other stars

In addition to stars like Alpha and Proxima Centauri,the constellation is known and other elements. For example, there is also Beta Centauri in it - a star of the first magnitude or, as it is also called, Agena, which in translation means "knee". Its other name is Khadar (translated as "land"). Like Alpha Centauri, it consists of several stars, but, unlike it, is located far from the Earth. Its distance from us is 525 light years.

On the level of brightness, Khadar occupies the night skythe tenth place. The third star of the constellation Centaurus is called Theta. It is also called Menkent, which means "centaur's shoulder". Its size is 2.06 magnitude, it is located more than 60 light-years from the solar system. It is worth mentioning such a famous star, included in this constellation, as Lucy, on scientific - BPM 37093. This white dwarf got its name due to the song of the group "The Beatles". The song is called "Lucy in the Heavens with Diamonds".

Other objects of the constellation

Constellation also boasts the presence ofobjects of the so-called deep space. That is, distant star clusters and nebulae. One such is the globular cluster numbered NGC 5139. It can be safely attributed to the most extensive and brightest in the Milky Way galaxy. It contains several million stars, which belong to the so-called population 2, that is, those that were found first in our starry sky. In the middle of this cluster, some stars are located to each other at a distance of less than one tenth of the light year. Also this cluster of stars is located to the solar system much closer than the others.

Another constellation Centaurus has a galaxy in the form oflens. Its number is NGC 5128. It has a very low degree of star formation, it lies between the spiral and elliptical type of galaxies. It mainly consists of the red stars that are at the stage of the last evolution. In terms of its brightness, it takes the fifth place.

Nebula can also be mentioned under the number NGC3918. Sometimes it is called "Southerner", and if you look at it in a telescope, it will look like a small blue circle that resembles the planet Neptune.

A small conclusion

The constellation of Centauri belongs to the familyconstellations of Hercules, is one of the longest known constellations, enveloped in myths and legends. But is it one such thing in the night sky? How many interesting, new, unknown things are hidden in the starry sky. His secrets caused a lot of legends and legends. Many astronomical facts are already known to mankind, such as, for example, the history of the origin of our planet. But up to now, the question remains whether we are alone in the universe. We still have to figure it out. Perhaps this will take not one hundred years. In the meantime, we can only guess at the existence of extraterrestrial civilizations.
