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. Now think about all the moons that orbit the planets, and the comets, and the asteroids, and everything else in the universe. That’s a lot of data and facts and figures. This article, which presents astronomy facts, certainly won’t contain every fact. But it will be a lot of fun.

How about the brightest stars as seen from Earth? Those are good astronomy facts. Let’s ignore the sun, it’s too close. 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 son is approximately 26.73, with the full moon weighing in at -12.6. All righty then, here’s the top five list.

#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 not the largest or brightest star in the universe or even the galaxy, yet it appears so bright because it is so near compared to other stars. You will obtain additional info on tasco 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, by the known astronomy facts is Arcturus. That’s the Greek word for Guardian on the bear. Arcturus is 37 light-years from Earth.

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 obtain heaps of supplemental valuable information relating to pentax binoculars here.

#1 is reserved for serious, meaning scorching in the Greek language. It’s also called the Dog Star because it’s the brightest star in the constellation Canis Major (the Big Dog.). At only 9 light-years away from Earth it is the second closest in these top five. It’s appears to be the brightest star in the sky, with a magnitude of -1.44.

There are many more astronomy facts out there. But it’s something to consider next time you look into the sky.
