Review Dog Days of Summer
Sirius, the Dog Star (pages 6 and 7)
Each of the dog constellations has one especially bright star, but the bright star in Canis Major is the brightest star in the night sky. Astronomers usually call this star Sirius. That is what the ancient Roman people called it. Many other people just call it the Dog Star.
There is one star that looks brighter than the Dog Star, but it's not a star you see at night. That star is the sun. The sun looks bigger and brighter only because it is much closer to Earth than any other star. The Dog Star is actually larger than the sun, but it is much farther away from Earth--more than half a million times farther.
