Derek C. pointed us to this piece of chartjunk on Wikipedia. This chart compares the mass of solar system objects, relative to the Earth's mass.
The bars are inappropriate, as their length is proportional to the
logarithm of the ratio of the masses of the object and the Earth. Also
the multiple colours are distracting.
I'm also mystified by the first bar called "Solar System". It seems to convey the idea that the Solar System is much larger than the Earth; combined with the second bar ("Sun"), it tells us that every object but the Sun pales into insignificance. If this is true, then the Solar System needs to be labelled differently as it is not a "solar system object".
Derek sent in a much improved chart:
His version is much cleaner. The axis labels, properly oriented, are much easier to read. The use of color is admirably restrained: I suspect that he is as baffled as I about the asterisks (now blue dots) in the original chart. I'd retain the vertical line through the Earth (relative mass = 1) to help anchor the chart.
But a job well done! He should send it in to the powers to be at Wikipedia.
