• Waterproof • Tear-Resistant • Stargazer Map and Guide The Moon's mystique for ancient cultures might have lain in its unchanging aspect as it traversed the celestial sphere. The same lunar face permanently looks down on Earth because of tidal locking. Thus we use the terms "Near Side" to describe the side always facing the Earth and "Far Side" to describe the side that had been hidden from humanity until the space age. The Moon Stargazer Map and Guide includes detailed maps of the Near and Far Side and helpful tips on Moongazing from Earth. Each feature is listed in a detailed index to help easily locate them across the Moon's surface. The map also includes the landing and crash sites of spacecraft that have visited the Moon from Earth. Graphics describing the Moon's phases, rotations, and both solar and lunar eclipses help explain these phenomenon. Earth's moon is not the only moon in our local solar system. A graphic on the map shows the relative size of moons from the Mars' tiny Deimos to the enormous Titan orbiting Saturn. Every Stargazer Map is printed on durable synthetic paper, making them waterproof, tear-resistant and tough -- capable of withstanding the rigors of repeated outdoor use.
