[Saturn and Beyond is another] in Asimov's series of astronomy books for junior high, misleadingly titled as always. The first three quarters of the book deal only with the planets known to the ancients, one supposes in order to use a historical approach, but then Asimov talks of the 1977 discovery of Chiron (an asteroid between the orbits of Saturn and Uranus) before admitting that Uranus was discovered in 1781. He spends a great deal of time on the various moons, discussing what one could see from them as well as the usual statistics about size and orbits, which makes the lack of mention of Pluto's newly discovered moon more noticeable. Asimov's Jupiter: the Largest Planet … is better organized to tell about the outer planets, but is becoming seriously dated as new information piles up, and should be replaced with Saturn and Beyond.
