Origin of Constellation 88: Who is Perseus?

Perseus in the constellation 88 is characterized by extending the diagonal lines of the quadrilateral Alpha Pegasus and Alpha Andromeda to twice the distance in autumn, and having a bright star with apparent magnitude of 1.8m, which is the brightest alpha star in Perseus. The most striking sign of Perseus is the great arc drawn by η star, which passes through γ, α, δ and ε stars and reaches ξ and ζ stars. People call it "the bow of Poerxiusi". China is called "the boat in the sky".

Introduction to Perseus

Perseus spans the Milky Way in autumn, so whether using binoculars or other telescopes, it is a good place for astronomy lovers to search for celestial bodies. There are many bright stars in this constellation. You can see the outline of the constellation even in the suburbs. The Milky Way is not as bright as Cygnus next to it in this galaxy. This enables people to see many bright star clusters, gas nebulae and planetary nebulae. This constellation has two messier objects: M34 and M76.

Heroes in Poerxiusi's mythology

Poerxiusi (or Poerxiusi), a hero in Greek mythology, is a symbol of Poerxiusi. Legend has it that the hero Poerxiusi is the son of Zeus.

Stepfather Poldeketes asked him to try to get Medusa's head. Medusa's head is covered with poisonous snakes, and anyone who looks at it will turn to stone. With the help of God, Poerxiusi put on winged shoes and an invisible hat. With the reflection of the bronze shield, she avoided her eyes and nodded and cut off the monster's head. Then he rode a flying horse that jumped out of the witch's body and left the danger. On the way back, I saved Princess Andromeda and married her. Finally, she dedicated Medusa's head to the goddess of wisdom. The goddess fulfilled her promise and lifted Poerxiusi to the sky, becoming Poerxiusi.

At the same time, it also raised the princess to the sky and became Andromeda. Therefore, they are always close in heaven. In the starry sky, Perseus is close to Andromeda and Cassiopeia (the princess's mother). This vast starry sky tells this famous Greek fairy tale. NGC869 and NGC884, two globular clusters, represent Perseus' right hand waving a sword; The beta star Perseus (Daling V) represents Medusa's head and is held in Perseus's left hand. The denser part of the galactic stars passes through here, and Perseus is a fascinating constellation for people who use binoculars.

In fact, Perseus also has a title called "Magic Star". The important reason why it is called "Magic Star" is that its brightness will change, flickering, just like a mysterious magic eye.
