orion
The brightest star in Orion is beta star, with an apparent magnitude of 0. 12, ranking seventh among all bright stars in the whole day, with an absolute magnitude of -7. 1 and a surface temperature of 12000.
The main body of Orion is composed of four bright stars, such as Betelgeuse and Betelgeuse, and there are three bright stars in the center of the quadrilateral in a straight line.
Think of Orion as a belt around the hunter's waist. In addition, under these three stars, there are three little stars, which are swords hanging on the belt. The whole image is like a hunter standing bravely, holding his chest high and looking up, which is very spectacular and has been noticed by people since ancient times. Where hunters wear swords, a blue-and-white hazy cloud can be seen with the naked eye. This is the famous Orion Nebula. At the left end of the hunter's belt, there is a dark nebula shaped like a horse's head, which is the famous horse's head nebula (unfortunately, it is invisible to the naked eye).
In every country in the world, it is a symbol of strength, fortitude and success, and people always compare it to God, warrior, superman and hero. Among the 28 hotels in Sanyuan, China, Orion is equivalent to Betelgeuse, Lisu, Shenqi and Shuifu.
There are three stars hanging high in the southern sky, so there is a folk saying that "three stars are shining high and the New Year is coming".
Note: The international constellation is 88, not (ecliptic) 12.
