The constellation problem that can be seen on the earth

Orion is the most magnificent constellation in the whole day and one of the zodiac constellations. ? Orion is located at the equator of the celestial sphere and can be seen in most parts of the earth, specifically between Gemini, Unicorn, Canis Canis, Taurus, Rabbit, Bojiang and Canis Minor, and its northern part is submerged in the Milky Way. The main body of the constellation consists of four bright stars, Betelgeuse and Betelgeuse, forming a quadrilateral. In the center of the quadrangle, there are three bright stars in a straight line, which should be a belt tied 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 brave hunter, with his head held high, which is very spectacular and has been noticed by people since ancient times. ? The constellation represents the hunter, and there are two dogs (Canis major and Canis minor) at its feet. As the earth rotates, Orion chases the Pleiades in the sky. There are many bright stars in Orion, but the most famous feature is the giant nebula M42 on Orion's sword, which is located in the south of Orion's belt and is lined with three stars.
