Constellation knowledge: a brief introduction to the northern corona constellation?

In astrology, there are many classifications of constellations. In addition to the twelve constellations and four constellations that we are familiar with, there are many classifications that ordinary people are more familiar with, such as the eighty-eight constellations. Then, today's constellation knowledge will bring you an introduction to the "Northern Corona" belonging to the 88 constellations. Let's have a look.

Introduction to the Northern Corona Constellation The Northern Corona is one of the stars in the north. The center position is at right ascension 15: 50 and declination 33. The area is about 179 square degrees. Between Capricorn and Wuxian. Near arcturus in Lyra, Vega and Shepherd, there is a 2.4m star, which is the alpha star in the northern corona. The seven little stars on the seat make up a beautiful crown, which is a wedding gift from Dionysus to Ariadne-a crown inlaid with seven gems. Celestial Name: CoronaBorealis Latin abbreviation: CrB symbol: Crown Right ascension: 16h declination +30 area: 179 area ranking: No.73 bright star: 1 brightest star: Guansos (northern corona α) meteor shower: unconnected constellation: Capricorn. The apparent magnitude fully visible region of the brightest star between 50: 2.2: 90 n-50 s.

There are 29 stars with brightness greater than 6 in the constellation, of which 1 is a second-class bright star, 4 are fourth-class stars, and the rest are less than 5-class stars. There are seven main bright stars on the seat, forming a C-shaped recumbent shape. These seven stars are: theta star (Chinese name "Kousuo II", 4. 17, etc. ), beta star (Chinese name "Kousuo III", 3.72, etc. ), alpha star (Chinese name "Kousuo IV", 2.23, etc. ) and gamma star (Chinese name "Kousuo V", 3.93, etc. These seven bright stars shine with white light, much like a gorgeous crown inlaid with precious stones.

Seven bright stars are counted from the east, three of which are alpha stars in the northern corona (named "Guansuo IV" in the middle). The Latin name Gemme, which means "the jewel in the crown" (also called Alqhecca, which means "broken plate"), is the biggest and brightest one in the crown. Alpha star is also an eclipse star, and its brightness varies between 2.23-2.2 1. There is a famous cluster of galaxies in the constellation, which is called "Northern Corona Cluster of Galaxies". There are about 400 galaxies 740 million light-years away from our extinction.

In ancient astronomy in China, the Northern Corona was described as a prison for prisoners, which was surrounded by nine bright stars, namely π-ρ. "Prison" has a variable star, and its brightness will suddenly drop from 5.7 1 to 14.8, which means that its brightness will change thousands of times during the dimming duration of several tens or hundreds of days. This star is yesterday's northern corona. Forty such variable stars have been found in astronomy, but the R star in the northern corona is the most typical one. This R star is almost invisible to the naked eye when it is brightest, and it will be invisible when it is darker. Astronomers in China before the Han Dynasty had noticed this variable star and thought it was a prisoner who was sometimes imprisoned and sometimes released. In our country, people call Beiguan "octagonal glazed well".
