Uranus [PDF ebook] 

With temperatures dipping to -366 degrees Fahrenheit and the theory that there may be a layer of diamonds below its surface, Uranus will fascinate any student. This book offers a detailed look at the planet’s magnetic field, climate, composition, and possibilities for life. Full-color images make this a wonderful read and a handy reference tool for young adults. This revised edition of Uranus includes new information on the first discovery of the planet’s rings almost 200 years earlier than believed, the 2005 discovery of a pair of rings and two small satellites previously unknown, and recently observed large clouds and a dark spot on the planet’s surface. This revision also includes updated references to Pluto’s new status as a "dwarf planet, " having been demoted from full planethood.
