| I like to think of a marathon as one AU. If the start line of the marathon happens at the center of the Sun, and the finish line is at the center of the Earth... You run for 213 yards to get out of the sun. You make it to the surface of the Earth at 5 feet, 10 inches from the finish line. (If the moon was eclipsing the sun, you would have run over it 122 yards from the finish line, and it would have a diameter of 3 feet, 2 inches.) And Pluto's orbit? Well, it's 859 miles from the start line. If the marathon had been in New York? It's kind of like running to Chicago. (It's a tad further than that.) Oh, and on this scale, how fast is light travelling? 188 miles per hour. The world record human marathon speed was 13 miles per hour. So, 7% of the speed of light. |
