The OMG SPACE website shows you the entire solar system in one, easy to scroll page. Except that... it's to scale, so you'll be pressing the space bar for quite some time to reach Earth.

All the planets on this website are to scale, including the sun and dwarf planets. The distances between each object and the sun are also to scale, and both the planets and relative distances are to scale with each other. Everything is calculated at a ratio of 1:647 to make easier numbers to work with and give me reasonable pixels sizes for this website. So if the Sun is 1,391,000 kilometers in diameter, then 1,391,000 divided by 647 equals 2149.92, and if I convert kilometeres to pixels where one kilometer is one pixel, my image of the sun is 2149 pixels squared. The same works for the distances: if Mercury is 57,909,050km from the Sun, with the ratio of 1:647, the distance is boiled down to 89503.94, so 89,503 pixels from where the Sun is placed on the screen. With everything calculate using the same ratio, all the sizes and distances are then properly to scale relative to one another.
