National Geographic Solar System Map (Stargazer Folded)
- Waterproof - Tear-resistant - Stargazer map and guide The name Solar System is derived from "Sol," or sun, and describes our planetary system orbiting our sun. The four terrestrial planets are closest to the sun: Mercury, Venus, Earth, and Mars. All are dense, with solid surfaces and iron cores, but conditions on them vary considerably—wet and temperate on Earth, icy and dry on Mars, and scorching and dry on Mercury and Venus. The outer solar system is where the gas giants reside. Jupiter and Saturn have almost all their atmospheres on small, dense cores. Uranus and Neptune appear to have much larger solid cores relative to their size beneath their hydrogen-helium veils. The Stargazer Solar System Map and Guide includes detailed images of the planets and a striking comparison of all the planets against the much larger Sun. A map of the planets shows their progression as they orbit the Sun, from Mercury's 88 days to Neptune's 165 years. Each Stargazer map is printed on durable synthetic paper, making it waterproof, tear-resistant and robust, able to withstand the rigors of repeated outdoor use. Sheet dimensions: 47 x 64 cm. Folded dimensions: 10.8 x 23.5 cm.
