The image above accompanies Steve Soter’s Scientific American article about the new definition of planets. The image of the solar system deals with the typical issues of scale and two-dimensionality adequately enough, but I really like the little graph just below the center. It shows Soter’s proposed μ values for various solar system bodies, which gives a more mathematical expression to the concept of a planet “clearing its orbit.” (Note that the scale of the bar graph is exponential!)
Now compare the graph to Figure 3 in the astro-ph version of the article. Whereas the astro-ph version uses a standard scientific convention (plotting two quantities and revealing μ as a diagonal line on the plot), the Scientific American version translates the concept into simple visual vernacular. Excellent work.
