Once thought to be a planet itself, distant Pluto is now called a dwarf planet. Tiny, rocky, cold Pluto stands guard at the edge of our solar system. It is so far away that even our most powerful telescopes can’t see it clearly. Readers will learn about Pluto and our efforts to discover more about this mysterious dwarf planet.
