The wide range of planets in our small solar system alone is remarkable—giant planets; dwarf planets; rocky, watery, and gaseous planets; frigid planets and blazing-hot planets; and planets surrounded by rings or multiple moons. Then travel beyond our solar system and begin exploring the so-called exoplanets, and the variety is even more dazzling. Even readers who think they know everything about planets will find much to intrigue, excite, and thrill them here, including fascinating facts, the latest findings, and eye-popping, full-color, high-definition photos and explanatory graphics. A must-have foundational resource for every burgeoning space scientist.
