How many astronomy facts are there for all the objects and phenomenon in the entire universe? To count the stars in the universe we need a one followed by 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. The number of facts and amount of data is staggering. This short discussion won’t cover everything. Walked is here, however, is interesting. Click over here for more info on fujinon binoculars
The data on the brightest star as seen from Earth are good astronomy facts. The son, about 250,000 times closer than the next star, isn’t counted here. 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. In the scale we’ll use the sun is 26.73, and the moon is -12.6. With that in mind, here are the top 5.
#5 is the Arabic word for eagle or vulture, Vega. 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. Our sun, for example, appears brighter than any other star, even though it’s not one of the brightest in the universe. That’s because it’s so close.

#4 is the Arabic foot of the centaur, Rigel Kentaurus. It scores a magnitude of -.01, and is only 4 light-years from Earth. At #3, by the known astronomy facts is Arcturus. The name means guardian of the bear in Greek. This star is 37 light years from us.
Canopus comes in at #2. Named for the pilots of Jason’s vessel in Jason and the Argonauts, this star is the brightest of all of these top five. 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. It’s appears to be the brightest star in the sky, with a magnitude of -1.44.
This information doesn’t even scratch the surface of astronomy facts. But consider it next time you see the stars in the night sky.
