Constellation roaming-Cassiopeia

Ethiopian Queen Casio Paya was very vain, boasting more than once that her daughter Andlau Meda was more beautiful than Poseidon's daughter, which angered Poseidon. Poseidon sent Cetus, a sea monster, to destroy the coastline of the kingdom. In order to avoid the intrusion of sea monsters, Andlau Moda was chained in the sea and sacrificed to the sea monsters. Fortunately, Poerxiusi saved Andlau Moda and married her. Maybe it's the light of the son-in-law. Casio Paya also ascended to heaven and became Cassiopeia.

Compared with her husband Cepheus, Cassiopeia is much more dazzling and easy to identify. In the south of Ursa major, there is a letter W consisting of five bright stars, which is Cassiopeia. Connecting these five stars with the other two stars is like a noble queen sitting in a luxurious chair. α is her chest, β and θ are her arms, ε is her feet, ζ is her face, and γ is her waist.

Among several clusters in Cassiopeia, the open cluster M52 is a cluster with high star density, with about 100 stars, which is very suitable for novices to observe.

The best observation time of Cassiopeia is 65438+ 10 month, 165438+ 10 month. Location: Northeast quadrant.
