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. This means you'll have to do a bit of scrolling if you want to find the planets, but don't despair. They are reasonably bright and labeled, so you can probably catch them flashing by in the blackness even if you are scrolling fairly fast.
(Note: users of older versions of Internet Explorer may not be able to scroll manually all the way to the right edge. If you want to actually see Pluto, you may need to click HERE.)
Speaking of Pluto, I know it's no longer technically a planet, but it's still included in this model for reasons of tradition.
