In over twenty dramatic, full-color photographs and a concise, easy-to-read text, award-winning author Seymour Simon gives us the latest information about this turbulent world, from its mysterious clouds of methane-ice to its raging winds of up to seven hundred miles per hour and its Great Dark Spot, a huge hurricane big enough to swallow our entire planet Earth. We also learn about the bright white cloud scientists have nicknamed "Scooter" and about Neptune's surprising moons, including pink, volcanic Triton-the coldest object ever measured in the Solar System.

Neptune is an exciting introduction to one of the most amazing mysteries in the universe.
