Distances and sizes are to scale, one pixel is 400km, making it by far the largest and most complete web-based scale model I've been able to find. Brightness (albedo) is not to scale, otherwise Mercury, Earth's Moon and the satellites of Jupiter would be far too dark to see clearly. This page is absolutely huge and may even crash some browsers. Internet Explorer has problems at Uranus and beyond, but doesn't crash, but I had to remove 90377 Sedna completely to make Firefox even display the page. At 96dpi, this page is 6.7km (4.2 miles) long out to Eris.

Radii are equatorial (or, for irregular and highly oblate objects, the mean diameter), distances are semimajor axis. When complete, all known objects larger than 400km (one pixel, adding the Kuiper Belt at the moment, bear with me there are a lot of 400km objects there) are presented and where possible actual imagery is used.
