All You Ever Needed To Know Relating To Astronomy
How many astronomy facts can you think of? Consider that there are somewhere around 1 x 10 ^22 stars in the universe, that’s a one followed by 22 zeros. Then consider that many of those stars have planets surrounding them. Then consider the moons that surround the planets, the asteroids, the nebula, the galaxies, and all the other stuff the universe contains. The number of facts and amount of data is staggering. This article, which presents astronomy facts, certainly won’t contain every fact. Walked is here, however, is interesting. Click over here for more info about celestron binoculars
Let’s take a look at this subset of astronomy facts the brightest stars as seen from Earth. That’s discounting the Sun which is about 250,000 times closer than the next nearest star. We get so much light from the sun that when it shines none of the other stars can be seen. Keep in mind that in the scale for the magnitudes given, lower numbers are brighter. The sun would be about -26.73, while the full moon is -12.6. All righty then, here’s the top five list.
#5 goes to Vega, Arabic for vulture. It’s about 25 light years away from the Earth, with a magnitude of .03. When looking at these astronomy facts remember that brightest from Earth doesn’t mean largest or brightest. The sun is only a moderately bright star, but because of its proximity to the Earth it appears to be so bright. You will obtain more valuable info about astronomy binoculars here.
#4 is Rigel Kentaurus, that’s Arabic for foot of the centaur. It sits about 4 light-years from Earth and has a magnitude of -.01. At #3, remember this is set in stone as one of the many astronomy facts we have, is Arcturus. That’s the Greek word for Guardian on the bear. This star is 37 light years from us.
Canopus comes in at #2. In reality it’s the brightest of all of these top five stars. But it’s 313 light years from Earth so it’s just second on this list as seen from Earth. It has a -.62 magnitude as seen by humans on this planet. You should acquire heaps of additional valuable info relating to canon binoculars here.
#1 is Sirius, meaning scorching in Greek. It’s also called the Dog Star because it’s the brightest star in the constellation Canis Major (the Big Dog.). Only 9 light-years separate Sirius and the earth, that’s the second nearest in this top five list. But from Earth it has a magnitude of -1.44. That makes it easily the brightest star as seen in the night sky.
Astronomy facts go way beyond this. Think about magnitudes, however, next time you look up at the stars.
