Can you find Orion?

Orion looks very much like a person. First, you should spot Orion’s Belt, which is made of three bright stars in a straight line. One of Orion’s legs is represented by the bright star Rigel, one of the brightest stars in the night sky. His two shoulders are made of the stars Bellatrix and Betelgeuse. You can see Betelgeuse’s reddish color without a telescope.
