Which is The Brightest Star in The Sky?
The brightest star in our sky is named ‘Sirius’. This is located in the constellation ‘canis Major’. This constellation is also called the `Great Dog’ and hence the star is also known as the Dog Star.
Because of its brightness, the Greeks called it ‘scorching’ which is the origin of the word sirius. Ancient astronomers noticed that sirius rose with the sun late in the summer. And the hot days of late summer were given the name ‘dog days’. The Egyptians worshipped this star as a god who helped farmers, because before the season of the Nile river floods this star was seen in the mornings.
Actually Sirius is no brighter than many of the other stars in the sky ; it appears bright to us because it is closer to the earth than some other big stars. It is only about 8 1/2 light years away & which means the light we see has left Sirius 8 1/2 years ago.
Sirius is not a single star but a double star.
‘Caropus’ is the second brightest star we see from the earth. It is many times much brighter than Sirius but is very far away -111 light-years away and hence look less bright.
