Pluto: A Double Planet

Pluto’s discovery in 1930 has excited our imaginations and quickened our desire for greater knowledge of the Solar system. Accompanied by its orbital sidekick, Charon, our “newest” planetary neighbor is also one of our most intriguing. Isaac Asimov introduces us to the beguiling questions surrounding Pluto, including its murky origins and uncertain status as a possible double planet.

Like How Did We Find Out About Pluto? this covers all the main points regarding the (former) ninth planet of the solar system, its discovery and properties. It makes for a rather jarring read, but it includes a fairly current and useful “Fact File” and is well-illustrated, and so is useful even for the adult who wants to look up information on Pluto.
