All You Ever Needed To Understand Relating To Astronomy
There must be a lot of astronomy facts right? Realize that the universe contains one times 10 to the 22nd stars, that’s a one followed by a string of 22 zeros. Now realize that many of those stars are surrounded by plants. 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 can be presented here. But these are interesting facts. Click over here for extra information about fujinon binoculars
How about the brightest stars as seen from Earth? Those are good astronomy facts. The son, about 250,000 times closer than the next star, isn’t counted here. The sun is so bright that it washes 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 son is approximately 26.73, with the full moon weighing in at -12.6. And now to the top five.
#5 is the Arabic word for eagle or vulture, Vega. This star has a magnitude of .03, and is 25 light-years from Earth. 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 find more information about astronomy binoculars here.
#4 goes to Rigel Kentaurus, or foot of the centaur. It sits about 4 light-years from Earth and has a magnitude of -.01. At #3, is Arcturus, according to the astronomy facts we know. In Greek that means guardian of the bear. It’s 37 light-years distant from our home on Earth.
#2 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. However, it’s 313 light-years away from Earth, so it looks second brightest as seen from this planet. -.62 is its magnitude is seen from the planet Earth.

#1 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. Only 9 light-years separate Sirius and the earth, that’s the second nearest in this top five list. At -1.44 magnitude it’s the brightest star we can see from Earth.
This information doesn’t even scratch the surface of astronomy facts. But it’s something to consider next time you look into the sky.
