If you're the type that is bothered by small details, you may not want to read page 102, where it says that Saturn's rings vary in thickness from 100 to 1000 meters. In truth, the rings are startlingly thin — ranging from 5 to 30 meters — with most rings sitting at just 10 meters thick. Also, if I recall correctly, the outermost ring is several hundred thousand kilometers wide. Of course, it's practically invisible in most photographs. It's the oddball of the group; the one that's not like the others. Oh well, it's a great book and setting in most every other respect.
