Alphecca [alCrB], the amazing experience of achieving what had been tried so many times

Alphecca [Alfa Coronae Borealis , alCrB, α CrB] is the brightest star in the constellation Corona Borealis (the Northern Crown), with a visual magnitude of +2,22. It is located at a distance of 75 light years from the solar system.

The traditional name of 'Alphecca' comes from the Arabic 'al-na'ir al-fakkah', which means 'the bright star of the broken ring'. In more recent times, it was also known as 'Gemma', which in Latin means 'gem' or 'jewel', whose possible etymological origin may be related to the term 'bud' (unopened flower, leaves of the floral crown). In China it was known as 貫 索 四 'Guàn Suǒ sì', which means 'the fourth star of coiled thong'.

Alphecca is a white main sequence dwarf star of spectral type A0 V, with a surface temperature of 9700 K. It has a rotation speed of 139 km/s.

  • Declination:  26.7º (26º43' 1st House)

Alphecca is a star that reminds the quality of the planets Uranus and Pluto, and also the centaur Amycus. The symbolic image 'ring' refers to a situation or circular process that ends and starts again, repeating indefinitely ('limit cycle attractor' in the theory of dynamic systems). Therefore, the symbolic image 'broken ring' refers to interruption of this kind of endless processes; It is equivalent to the classic theme of the fairy tales of 'breaking the curse'.

Alphecca is related to the amazing experience of achieving what had been tried so many times.
