Shaking lights and Sirius's explanation?

Yaoguang, also known as the Big Dipper and Broken Army Star, is regarded as one of the stars symbolizing good luck. Among them, the name "Broken Army Star" is the product of the combination of China's folk theory of Yin-Yang and Five Elements with astronomy, with strong elements of divination and fortune telling.

Sirius is the alpha star of Canis Canis, the brightest star except the sun in the whole day, but darker than Venus and Jupiter, and brighter than Mars most of the time. Sirius generally refers to Sirius A and Sirius B, with a radius of about 4900KM. Sirius b was originally composed of carbon and oxygen, which was produced by helium fusion in the death star that formed Sirius B.

These elements are covered by lighter elements and layered according to mass, because Sirius B has a great surface attraction. So Sirius B's outer atmosphere is almost pure hydrogen, which is the lightest element in the universe, and no other elements can be found in the spectrum.

In western culture, this star is customarily called Alkaid (also called Elkeid, from Arabic) or Benetnasch? . Alkaid comes from an Arabic phrase.

In Arabic culture, this is a sad image of a leader's daughter beside her father's coffin. Also as the daughter of this leader are two other stars on the handle of the Big Dipper: Kaiyang and Yuheng. Tianquan, Tianqi, Tian Xuan and Shu Tian are the spoons of the Big Dipper and are considered as the coffin of this leader.

In 20 16, the International Astronomical Union organized the Working Group on Star Names (WGSN) to catalogue and standardize the proper names of stars. WGSN released its first report on July 20 16, including a list of the first two stars approved by WGSN, including Alcaide.
