The Dude was browsing some science sites, and found a site which illustrates the sizes of some stars and planets. After a little additional reading, it may not be strictly correct (ie. the exact size of some of the stars evidently in a bit of doubt) and so the order may need to change a little, but even then, it does do a great job of indicating how small Earth really is. If you think that was interesting, this is an attempt to show a scale model of a hydrogen atom— it is a web page that is 11 miles wide, so don’t print it at home.
