Bill Nye Demonstrates Distance Between Planets
"Richard Dawkins wrote this about our planetary system:
Find a large open space, and take a soccer ball to represent the sun. Put the ball down and walk ten paces in a straight line, stick a pin in the ground. The head of the pin stands for the planet Mercury. Take another nine paces beyond Mercury and put down a peppercorn to represent Venus.
Seven paces on, drop another peppercorn for Earth. One inch from Earth, another pin head represents the moon, the furthest place, lets remember, that we have so far reached.
Fourteen more paces to little Mars and ninety five paces to giant Jupiter, a ping pong ball. One hundred and twelve paces further, Saturn is a marble.
No time to deal with the outer planets, except to say the distances are much larger. But how far would you have to walk to reach the nearest star, Proxima Centauri? Pick up another football to represent it and set off on a walk for four thousand two hundred miles.
As for the nearest other galaxy, Andromeda, don’t even think about it."
Solar System Scale Model
This page shows a scale model of the solar system, shrunken down to the point where the Sun, normally more than eight hundred thousand miles across, is the size you see it here. The planets are shown in corresponding scale. Unlike most models, which are compressed for viewing convenience, the planets here are also shown at their true-to-scale average distances from the Sun. That makes this page rather large - on an ordinary 72 dpi monitor it's just over half a mile wide, making it possibly one of the largest pages on the web.
