Why do you think it is important to have some knowledge of astronomy? What is the value of knowing a bunch of astronomy facts? The simple answer is because its a subject that a large number of people are interested in - and if you want to be able to talk to them about it, the odd fact never goes astray. In fact, its really important to know at least a few astronomy facts - you never know when you will be needing them - it might be at a party, at your school or while you are trying to impress that cute girl - who knows the exact reason - but it is very likely that you will need them at some point or other…… its magnitude is 62 as seen from the earth.

#5 is Sirius, meaning scorching in Greek. Sirius is also known as the Dog Star because it's the brightest star in the constellation of Big Dog. It's only 9 light years from Earth. That's second closest of these top five. At -1.44 magnitude it's the brightest star we can see from Earth.

There is a whole host more information about astronomy that we haven't discussed as yet. But it's something to consider next time you look into the sky. You can obtain additional worthwhile info on binocular astronomy here.
