Just as astronomers disagree with one another as to the distance of the planets, so also are they at odds in determining their sizes, as is evident from Book I, Chapter 25. Thus Tycho Brahe asserted that Saturn is at least twenty-two times larger than the earth while Riccioli said it ...
Then we compare the sizes of the planets, classify them as inner and outer or as rocky vs. gas. This takes about 45 minutes. More fall colors in Sardine Canyon as we drove to Logan. The final lesson, often used as an add-on to the scale and proportion lesson, is to talk about how...

The accumulation of ices partly accounts for the large sizes and low densities of the outer planets. The two most massive planets, Jupiter and Saturn, had surface gravities sufficient to attract and hold large quantities of even the lightest elements—hydrogen and helium. 8. What can be ...
