I also like this solar system model from NASA, https://science.nasa.gov/learning-resources/how-big-is-the-s.... They compare it to a US football field. "On this scale, the Sun, by far the largest thing in our solar system, is only a ball about two-thirds of an inch (17 millimeters) in diameter sitting on the goal line — that's about the width of a U.S. dime coin. ... The inner planets — Mercury, Venus, Earth and Mars — are about the size of grains of sand on a football field scale. They would be dwarfed by a typical flea, which is about 3 millimeters long. Closest to the goal line is Mercury, just under a yard from the end zone (.8 yards to be specific). ... At this scale, Mercury's diameter would be scarcely as large as the point of a needle. Venus is next. It is 1.4 yards from the end zone. ... On to Earth, sitting pretty on the 2-yard line. ... Mars is on the three-yard line of our imaginary football field. ... Jupiter remains pretty close to our end zone on the 10.5-yard line. ... Saturn is on the field at 19 yards from the goal line. ... Uranus ... is about 38 yards from our end zone. Neptune is where things start to get way out. It is 60 yards from our solar goal line on the imaginary football field. ... Tiny Pluto is much closer to the opposing team's end zone. It's about 79 yards out from the Sun ... On this scale, our little friend Voyager 1 has left the game and is well out in the stadium parking lot or beyond." | ||

It's illegal to mention the solar system and football without mentioning one of the greatest pieces of science fiction on the two, Jon Bois' 17776 https://en.wikipedia.org/wiki/17776 | ||
