This is sort of a mini-post to follow up my Clarence DeMar marathon post. I saved each of my mile splits from my race on my watch and decided that I wanted to present them in x-y axis form:
Take away point: I started the race too fast and my average pace is comparable to the radial velocity signal of a Neptune-sized planet orbiting 4 times closer to the Sun than Mercury does. The radial velocity signal is a measurement of the pull of the planet (due to gravity) on the star. It looks like this.
When you put things in terms of giant planets, 4 meters per second seems more impressive.
