Of the 88 constellations in the whole day, Orion is a familiar one. On winter nights, in the unpolluted clear night sky, people can easily find it. So, does Orion belong to the Milky Way? Let's have a look.

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 first thing that can be determined is that Orion is outside the solar system where humans live. Orion is made up of stars in several different galaxies, which is an area on the celestial sphere in the center of the earth, but it looks just together in the sky. In Orion, all the stars visible to the naked eye are located in the Milky Way, and the distance between them is very far.

As we all know, the Milky Way currently has four giant spiral arms, namely Sagittarius spiral arm, Orion spiral arm, Perseus spiral arm and Cygnus spiral arm. Our solar system is located on the arm of Orion between the arm of Centauri and the arm of Perseus, about 26,000 light years away from the center of the Milky Way.

Conclusion: At present, all the stars that make up Orion are basically members of the Milky Way. The Great Orion Nebula M42 is located on a spiral arm of the Milky Way, about 1500 light-years away from the solar system, and it is the nearest star birth place in the Milky Way.
