"Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour..."

Well, I made it! 58 times around the sun is quite a long journey.

Let's see - um we are an average of 93 million miles from the sun, and our orbit is more or less circular, so that's - um - two times Pi times the radius - um - 584 336 233 miles around?

And as the Solar System, too, is travelling around the galaxy, the earth doesn't do a closed orbit (as it is normally drawn) but a long spiral.

And I have done that 58 times. So that's 33 891 501 514 miles through the cosmos. Phew, I think I'll have to go and lie down (which doesn't stop us all travelling along at some blazing speed which I am far to exhausted to calculate).

OK, this site says we are doing 30km a second around the sun, and the solar system is going around the galaxy at 250km a second - you work it out....

And here we all are, arguing about resources on Spaceship Earth. And now we even have an operating manual.

"So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger all down here on Earth."
