It can be interesting to see things of extreme sizes put in some kind of perspective so that we can more or less relate to their actual scope.
Sometimes these extreme things are very large. Here in my community we have the world's largest scale model of the solar system, 80 miles in diameter. The Sun is represented by the dome inside our local planetarium and is 36 feet in diameter. The planets are located at various community public locations and businesses. They are placed at scale distances and are made in scale sizes to that Sun. Pluto is located at a furniture store in a smaller community about 40 miles away, and true to scale, is about an inch in diameter. (Google for more.)
And sometimes these things of extreme size are very very small. Represented on a single web page 11 miles wide you can see a scale model of a hydrogen atom.| And you thought there was a lot of empty space in the solar system. Well, there's even more nothing inside an atom. A hydrogen atom is only about a ten millionth of a millimeter in diameter, but the proton in the middle is a hundred thousand times smaller, and the electron whizzing around the outside is a thousand times smaller than THAT. The rest of the atom is empty. |

| Oh, how fun. We have one of those where I live. I'm just a few blocks from Saturn! |

My astronomy club made a similar scale model of the solar system in our town. But we made it smaller.
The sun has a diameter about 1.5 meters, Earth is about 1cm in diameter, and Proxima Centauri is exactly one lap around the world. Pluto is about 3mm about 2-3km away. I don't recall the exact numbers... |
