And in the last decade, when I find that shop assistants can't multiply by 10 in their head (i.e. add a zero to the figure), I've been wondering the same thing.

Anyhow, I rarely have a motor drive on my telescopes. So when the moon or planet goes out of the field I say
"See how it moved out of view?"
"Yes"
"It's not moving at all, it is standing still - that's actually us moving on the spinning earth".

It amazes them every time.

Actually, a teacher would explain that all planets move, but what you see through a telescope is primarily the effects of the earths rotation magnified by the telescope... If planets stopped moving in their orbits, I suspect they would plunge into the sun under the influences of the suns gravity.... BUT I COULD BE WRONG

Its just amazing what some people believe.
