Trying to imagine the size of our solar system is difficult, but this stunning full-color poster will help your students see the relationship between planets both in distance from the sun and relative size. The scale used to show planet diameters is 1 mm = 1,000 km, and the scale used to show distance from the Sun is 1 mm = 2 million km. Statistics for size, length of a day, and length of a year are also included for each planet. In addition, the poster shows comets, asteroids, spacecraft, and moons. It comes with instructions. Over 12′ long.
