Orion

The Orion constellation is known for having some of the brightest stars in the night sky. On a clear night, try to find the three stars that form the "belt" of the hunter. Above and below the belt you'll see Betelgeuse and Rigel. Betelgeuse looks reddish and Rigel is blue. The cloudy area just below the belt is the Orion Nebula—the closest major star-forming region to Earth.

and Taurus
Shape: three bright stars close together form the "belt" of Orion, the hunter
Significance: constellation easily found from the Northern Hemisphere
Distance: stars range from 520 to 2,100 light-years from Earth
