The Great Pluto Debate

At the edge of the solar system, beyond the bright planets we see in the night sky, lies one of the most fascinating worlds ever discovered. It’s small, icy, and once considered the ninth planet-until everything changed. Scientists debated its status, spacecraft traveled billions of miles to see it up close, and discoveries made headlines around the world.

This book takes young space explorers on an exciting journey to uncover the mysteries of this distant world. Learn how it was found, why it was called a planet for decades, and what makes it different from the other planets in our solar system. Find out what Pluto’s surface is made of, why its atmosphere appears blue, and how a giant heart-shaped glacier surprised scientists. Discover how Pluto and its biggest moon, Charon, act like a double planet system, and explore the strange world of the Kuiper Belt, where frozen objects orbit far from the Sun.

With fun facts, mind-blowing discoveries, and real NASA images, this book makes space science easy to understand. Whether it’s a planet, a dwarf planet, or something even more special, Pluto remains one of the coolest places in the solar system.
