Pluto plays a crucial role in studying the outer solar system, particularly in understanding the Kuiper Belt, where it resides. As one of the largest and first-discovered objects in this region, Pluto serves as a key example of a Kuiper Belt Object (KBO). Studying Pluto helps astronomers understand the composition, formation, and evolution of other KBOs. Its unique orbit, geological features, and atmosphere provide insights into how objects in this distant region interact with solar radiation and the rest of the solar system. Pluto's exploration, especially through the New Horizons mission, has shed light on the diversity and complexity of objects in the outer solar system, challenging previous notions and expanding our knowledge of these distant worlds.
