Interesting Astronomy Info That You May Not Know.
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…… Have you any idea how much astronomical data is physically available?? To count the stars in the universe you need a one followed by 22 zeros and an awful lot of time. Think about this, there are planets orbiting many of those stars.
Then consider all the moons that orbit the planets, the comets and asteroids, the galaxies these stars form, the nebulae and black holes and everything else out there. That’s a lot of data and facts and figures. Not every piece of information will be presented here. But these are some of the interesting facts.

Let’s take a look at a subset of information about astronomy the brightest stars as seen from Earth. That’s discounting the Sun which is about 250,000 times closer than the next nearest star. It’s so bright as seen from Earth that it washes out all the other stars in the sky during a phenomenon called daylight. Keep in mind that in the scale for the magnitudes given, lower numbers are brighter. In the scale we’ll use the sun is 26.73, and the moon is -12.6. OK then, here’s the top five list.
#1 is Vega, which means vulture or eagle in Arabic. This star has a magnitude of .03, and is 25 light-years from Earth. 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’s about four light years from Earth with a magnitude of -.01.
At #3, by the known information about astronomy is Arcturus. The name means guardian of the bear in Greek. Arcturus is 37 light-years from Earth.
Number 4 is Canopus. Of these top five Canopus, a Greek name for the pilot of the vessel Argo made famous in the stories about Jason and the Argonauts, is the brightest. But it’s 313 light years from Earth so it’s just second on this list as seen from Earth. From earth its magnitude is -.62|its magnitude is 62 as seen from the earth}.
#5 is the Greek word for scorching, Sirius. Because it’s the brightest star in the constellation Canis Major, it’s also called the Dog Star. 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 much more information about astronomy out there. But consider it next time you see the stars in the night sky. You can get complimentaryworthwhile info relating to zeiss binoculars here.
