People have been baffled, bewildered, and even outraged by the fact that Pluto is no longer called a planet. Who made this decision and why? If not a planet, then what is Pluto? Through whimsical artwork and an entertaining story, Pluto’s Secret introduces readers to this ever-popular icy world, from its discovery and naming to its recent reclassification. Published in association with the Smithsonian National Air and Space Museum, Pluto’s Secret presents a fascinating look at how scientists organize and classify our solar system. As they learn more about how it works and what types of things exist within it, scientists are constantly having to rethink how we see and understand things.

Sun . . . there has been a little icy world circling the sun, farther away than any of the planets. This icy world had a secret—a clue about something that exists in the solar system and the universe. But for a long time, no one on Earth could see this icy world. It was too far away and not bright enough to be seen in the sky. And so no one learned its secret.
