Orion is the most magnificent constellation in the whole day.

The alpha star Orion (Betelgeuse) is a red Supergiant star with brightness ranging from 0 to 1.3, with a period of about 6 years, and the average brightness is 10 bright star in the whole day. It is 430 light years away from the earth. The name Betelgeuse in the west comes from * *, which means the position of the hand, but in fact Betelgeuse is on Orion's shoulder. The beta star Orion is a blue Supergiant star, 0. It is about 770 light years away from the earth.

Orion θ 1 is a cluster star named Orion Quadrupole, which is located in the center of Orion Nebula. Four stars can be seen with a small telescope, arranged in an equilateral quadrangle, with brightness of 5. 1, 6.7, 6.7, etc.

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. Imagine Orion.
