Editorial Reviews

Children's Literature - Barbara L. Talcroft
Originally published in Australia, this "New Solar System" series delivers the latest astronomical news through 2008, illustrations on every page, and many statistics. In five or six brief chapters, young scientists will learn about the planets and other heavenly bodies, such as small revolving objects called dwarf planets since 2006—tiny Ceres (an asteroid), Pluto (formerly designated a planet), and grey, distant Eris. In Dwarf Planets, readers discover that Ceres, which is named for the Roman goddess of agriculture, orbits the sun in the asteroid belt between Mars and Jupiter; and we can occasionally see Ceres without a telescope. Pluto, named for the Roman god of the underworld who is shown in a statue with his three-headed dog, revolves in an elliptical, tilted orbit and has one large moon, Charon, and two smaller ones. Icy Eris, named for the Greek goddess of discord, and its moon Dysnomia revolve slowly about the sun in an off-center orbit; Eris was found in photographs taken through a telescope, while Dysnomia was discovered with a laser guide system at an observatory in Hawaii. For those intrigued by space exploration, the author explains that dwarf planets have not yet been visited by space probes, though one is on its way to Pluto and another is being contemplated for Ceres in 2015. Clear, no-nonsense text moves along briskly, while illustrations, usually eye-catching, are here somewhat dimmer. Further help includes a "Dwarf Planets Fact Summary," a glossary, and a list of websites. Reviewer: Barbara L. Talcroft
