The origin of Andromeda?

Andromeda is the daughter of Cassiopeia, the fairy queen in Greek mythology. The fairy's head is Cedius, a corner of the Pegasus quadrangle. [Edit this paragraph] Myth Story In Greek mythology, Andlau Moda is the daughter of Cepheus and Cassiopeia, the king and queen of Ethiopia. Her mother has offended Poseidon's wife, Poseidon, by constantly showing off her beauty. Neptune wanted Poseidon to avenge her, and Poseidon sent a whale to ravage Ethiopia. Cepheus is terrible and asked.

She was chained by her parents to a boulder on the road, and the sea monster represented by Ceylon constellation passed by. Later, the hero [[Poerxiusi] happened to catch a glimpse of the tragedy, so he immediately took out the head of Medusa, a snake-haired witch, and turned it into a fossil of Ceylon. Poerxiusi killed the sea monster and rescued her.

Later, Andlau Moda gave birth to six sons for Poerxiusi, including Poerxiusi, the founder of Persia, and Gorgo Feng Te, the father of King Tindarius of Sparta.

Andromeda's hands are bound by chains in the original map of Uranographia. [Edit this paragraph] Constellation characteristics

Andromeda has a main galaxy, M3 1 (Andromeda), which is one of the largest members of this galaxy group. Andromeda is characterized by two curves starting from Alpha, and you can easily find it from the connection between Cassiopeia and Polaris.

Undoubtedly, the most famous galaxy in Andromeda is M3 1, which is an extragalactic galaxy and a galaxy as huge as the Milky Way. M3 1 is about 2 million light years away, and it is the farthest celestial body visible to the naked eye. M3 1 was once considered as a nebula, and the identity of its galaxy was not confirmed by Edwin Hubble until 1924. If we observe with simple binoculars, we can find that M3 1 is surrounded by two companion galaxies: M32 in the south and M 1 10 in the north.

Among these interesting celestial bodies, it is certain that Andromeda γ is a binary star system, which consists of an orange giant star and a blue small star (as can be seen from the movement of γ star, but it requires some equipment). NGC 752 is also noteworthy. It is a huge open cluster, which contains more than 9, 100 stars, some of which are barely equal to 9, and the brightest is 8.54 (SAO 55080). There is a brighter star in the direction of the cluster, such as 8.07 (SAO 55 10 1), but it is not a member star and just coincides with the celestial sphere. The planetary cloud NGC 7662 can be observed with small equipment.
