Information About Astronomy – What Do You Be Aware Of Relating To Astronomy?
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…… There must be a lot of information about astronomy you would believe – right? Consider that there are approximately 1 x 10 ^22 stars in the universe, that’s a one followed by all 22 zeros. Think about this, there are planets orbiting many of those stars.
Now think about all the moons that orbit the planets, and the comets, and the asteroids, and everything else in the universe. It’s a lot to consider. Not every piece of information will be presented here. It will be a lot of fun. Click through here for more info on astronomical binoculars.
How about we consider the brightest stars as seen from Earth? They represent good information about astronomy. That’s discounting the Sun which is about 250,000 times closer than the next nearest star. The sun is so bright that it simply smothers out all of the other stars in the daylight sky. For the purposes of this discussion, lower numbers for brightness mean a brighter star. The sun is approximately 26.73, with the full moon weighing in at -12.6. And now to the top five.
#1 is the Arabic word for eagle or vulture, Vega. As seen from Earth its magnitude is .03. Just because a star looks brighter from Earth doesn’t mean it’s really brighter. The sun is only a moderately bright star, but because of its proximity to the Earth it appears to be so bright.
#2 is Rigel Kentaurus, that’s Arabic for foot of the centaur. It scores a magnitude of -.01, and is only 4 light-years from Earth.
At #3, by the known information about astronomy is Arcturus. In Greek that means guardian of the bear. Arcturus is 37 light-years from Earth.
#4 is Canopus. In reality it’s the brightest of all of these top five stars. However, it’s 313 light-years away from Earth, so it looks second brightest as seen from this planet. It has a -.62 magnitude as seen by humans on this planet|its magnitude is 62 as seen from the earth}.
#5 is reserved for serious, meaning scorching in the Greek language. 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. It’s appears to be the brightest star in the sky, with a magnitude of -1.44.
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 should obtain complimentaryworthwhile info on leupold binoculars here.
