Planets
When we were learning about our solar system in science class, I was surprised to learn that our solar system isn't shaped like the 3-D models you typically see. If the sun is about 3 inches wide, you can barely see any of the planets smaller than Neptune, and even Jupiter is just a little dot. On top of that, while the first 4 planets are densely placed (by universal terms) the rest are much farther apart. Also, the closer a planet is to the sun, the faster it has to orbit because it needs to balance centrifugal force with the sun's gravitational pull, or else it either gets sucked in or flung out of the solar system. There is also an asteroid belt where a planet should be, so there are theories that say a planet blew up, creating the asteroids.
