A friend asked me what the numbers in the following image represent:
Mercury 8 Venus 15 Earth 61 Mars 33 Ceres 42 Jupiter 42 Saturn 100 Uranus 22 Neptune 57 Pluto 85
My (limited) guesses on what the figures could be turned up nothing. I'm guessing since Saturn is 100, that the figures are expressed as a % of whatever the figure is for saturn? I'm pretty stumped for this.
Any idea what the numbers stand for?
