The phases of the Moon determine so much about what we can observe in the night sky on any given night. This fabled celestial object--the largest and brightest in a sea of astronomical wonders--is a fixture in poems, stories, and our imaginations. It is also a source of mystery and intrigue, despite its close proximity to Earth. To help you forge a deeper understanding of our neighbor that orbits some 240,000 miles (385,000 kilometers) away, we have created this portable reference. It features a simplified overview of such details as surface features, phases (and how these affect gravitational pull on Earth), eclipses, myths, and viewing tips. Especially engaging is the sharply illustrated map showing prominent craters, mountain ranges, seas, highlands, and landing sites from the Apollo missions. Laminated for durability, this lightweight, 12-panel folding pocket guide is a terrific resource to keep in your pocket or backpack during your next night-viewing session. Perfect for educators, learners, and astronomers of all experience levels. Made in the USA.
