Not to scale: It is hard to fathom the size of our solar system. If we wanted to create a model to scale, we might start with our Moon the size of a BB. At that scale the Earth would be about the size of a dime and the Sun would be a 6-foot ball [the size of a large dining room table]. We could construct a little community park to house our display with our 6 foot Sun in the center, and our dime-sized Earth would have to be about 700 feet away [nearly 2 1/2 football fields] with our BB Moon circling our dime-sized Earth about 21 inches from it. All doable, right? Then, we would need to put our sesame-seed-sized Pluto about 5 miles on past our model Earth, with the other planets strung out along that 5 mile line from Pluto to the Sun. Now, we would likely want to place Proxima Centauri [our nearest star, which could have just as easily been another solar system] into our scale model... That gets a bit harder. You would need to start traveling in any direction around our real Earth until you come back to where you started. Then, keep on going to the other side another half its circumference away. Place our nearest 2 foot model neighboring red star or Sun there. Big galaxy, huh? Pluto is over 3 1/2 billion miles from the Sun and Proxima Centauri is 25 trillion miles away. It takes our Sun's light 8+ minutes to reach Earth, 5 1/2 hours to reach Pluto, and 4 1/4 years to reach Proxima. That star could go black today and we would still be able to view its past existence for over 4 years. And remember, that's just our "closest" star! Our model above displays orbital rates using square-root compression. Faster inner planets still show as faster, while the outer planets still visibly move. If not altered, the inner planets in our model would move too fast to see and/or the outer planets would not appear to move at all. Orbital distances are greatly compressed to fit the display, causing our model moon to appear to occasionally bump one of our neighboring planets.
