Did the earth move for you?

If you were to add up all the motions of the Earth over a given period of time, how far would it have moved?
Lessee: it spins at 1000 mph at the Equator (don’t forget to compensate for latitude), it orbits the Sun at 18 miles per second, the Sun orbits the Galactic center at about 200 mps, and the Galaxy is moving toward th Andromeda Galaxy while simultaneously falling into a massive cluster of galaxies called The Great Attractor. Oh — the Universe is expanding, with the visible edge receding from us (or equally, we are receding from it) at the speed of light.
So if you take some given amount of time, you can calculate how far you moved during that time.
Still, that’s a bit dry. How to make this exciting to the average person?
