Stargazing（观星）takes imagination. People who love stargazing see the stars as shining spots in a dot-to-dot（点对点）drawing game. They imagine lines that connect groups of stars called constellations. A constellation is a group of stars that looks like a person, an animal, or an object.
The constellation Orion is known as the hunter, after a hero from ancient Greek stories. To find Orion, first find the Big Dipper. The Big Dipper looks like a huge cup with a long handle. After you find the Big Dipper, turn around. There’s Orion! He is outlined by four bright stars that form two triangles. The tips of the triangles seem to come together. Where they meet, there are three more bright stars.
Different kinds of stars are in the constellation Orion. The star Betelgeuse makes Orion’s right shoulder. Betelgeuse is an Arabic word that means “shoulder of the giant（巨人）.” The star itself is so huge that it is called a supergiant. Its diameter is 400 times greater than that of our sun. Betelgeuse is considered a cool star. It is probably not as hot as our Sun. Rigel is the star that makes Orion’s left foot. Rigel is the Arabic word for foot. Rigel is much brighter than Betelgeuse because it is much hotter. It’s more than three times as hot as our Sun. However, Rigel is just a baby in size compared to Betelgeuse.
