Our Solar System

Born almost 5 billion years ago at the edge of the Milky Way galaxy, our solar system is a place filled with mystery and wonder. 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, Our Solar System takes young readers on a fascinating tour of the sun, the eight planets, and their moons, plus asteroids, comets, and meteoroids. Award-winning science writer Seymour Simon has teamed up with the Smithsonian Institution on this new, updated edition of his much admired book about the vast and mystifying part of the universe that we live in.
