Astronomy Facts

For most people astronomy is an interesting science filled with many astronomy fun facts. Everything from the size and temperature of our own star, the Sun, to the makeup of distant planets has been established. All of this information can be retold to entertain and enlighten people.

The Sun is a great source of astronomy fun facts. Our own star that provides us with all our heat and light is between 91 and 94.5 million miles from Earth. It’s not that nobody knows the distance for certain. It’s that the Earth orbits the Sun in an elliptical, uneven, orbit, so the distance varies depending on where the Earth lies in that orbit.

The Sun is only an average size star, yet it’s size is another terrific source of astronomy fun facts. As average as it is, it accounts for about 98% of all the matter in our solar system. Even with the massive planet of Jupiter on our side, we’re still only a tiny 2% of non Sun stuff.

It would take the diameter of about 100 Earths to stretch across this average Sun. The solar winds created by the Sun extends to about 50 times the distance from the Earth to the Sun. Or put another way, those solar winds reach out about 50 AU’s, with an AU being the distance from the Sun to the Earth. That’s quite fantastic, isn’t it?.

How about astronomy fun facts that don’t have much to do with the Sun then? What about our Moon? It’s the only non-Earth object that man has walked upon so far. And one man actually travelled to the Moon but never left it. Dr. Eugene Shoemaker really liked the Moon but was rejected as an astronaut. After his death, he was cremated and his ashes were scattered over the Moon by the Lunar Prospector spacecraft in 1999.

There are lots more astronomical fun facts about the Moon. It’s where what might become the oldest footprint known to man. Neil Armstrong’s giant leap for mankind left a footprint or shoe print in the Moon’s dust that will probably still be there in 15 million years time.

Many people, in fact about 13% of those polled in 1988, still believed the Moon to be made of cheese. And finally, the suits worn by the Moon-walking astronauts weighed 180 pounds on Earth but only 30 pounds on the Moon, because of the Moon’s reduced gravity. Talk about losing weight, eh?

Astronomy fun facts aren’t limited to our close astronomical neighbours. Looking at stars is like looking into the past. Some of the stars we see today in the night sky are so far away that their light takes a million years to get to us. Some of the stars you see may literally be images of stars a million years old that aren’t even there any more. There are more than 1 x 10 ^22 stars in the universe. That’s a 1 followed by 22 zeros. The number is really quite awesome.

There are millions of astronomy fun facts and we could relate them forever. But unfortunately, this article can not. So, please, just get out there and learn more about astronomy for yourself.
