Why racing and why fellow space traveler?

Well, hang on to your hat and keep the dramamine handy.
 Our home planet rotates every day, as you may have noticed. As it is some 24900 miles around at the equator, my blog readers at the equator will be spinning at about 1037 miles per hour. Well, in truth, I don’t think I have any blog readers at the equator so we’ll use Austin,Tx. Presumably, I have a reader or two in or near Austin.
The earth isn’t quite as fat where Austin is so the rotation isn’t quite as fast. Its about 898 miles an hour.
(You people in Harlingen and McAllen are going a smudge faster.)
Now we’re just getting going. Our earth revolves around the sun. That’s at a speed of about 66,660 miles per hour. (This is the same for you no matter where you live.)
Then our solar system is moving around the galaxy. This is at about 8570 miles per hour.
Now bear with me. Our galaxy is moving within a local cluster of  galaxies at some 1490 miles per hour and that local cluster is itself moving within a larger cluster of galaxies at 22,356 miles per hour.
There is probably some movement beyond this but I didn’t get any farther. The only one I’m really sure about is us rotating every day. I guess we just have to believe them when they tell us about all of the other movements.
Now different astronomers compute some distances and times a little differently and they use terms like light years and parsecs and kilometers. I don’t really understand light years and parsecs and I barely understand kilometers. I am an American afterall. We use real measurements like yards and first downs and miles. Supposedly the metric system is better, but I wonder. A kilometer  equals .621371192 miles. Now, I ask you – is that simpler?
So I guess what I’m trying to say is that I did the conversions and computations to make this more understandable for you. You did find it understandable, didn’t you?
