The following plots give information about the masses and sizes of the planets. The top plot shows the masses of the planets as a function of their distance from the Sun. The bottom plot shows the masses of the planets as a function of their volume; note that the points are no longer ordered by distance from the Sun, but the color coding is the same as in the top plot. The dotted line shows where objects would fall if their masses were directly proportional to their volumes.

Considering the bottom plot, do you think all of the planets are made of the same material? If not, which planets appear to have the most different compositions?
