In the last fifty years, we have learned more than ever about the farthest reaches of our world. With dramatic full-color photographs and spacecraft images, <i>Our Solar System</i> takes young readers on a fascinating tour of the sun, the eight planets, and their moons, plus asteroids, comets, and meteoroids.
