Final answer:
Pluto is one of the largest members of the Kuiper Belt, which is a region of space beyond Neptune filled with icy objects and dwarf planets.
Step-by-step explanation:
From its orbit, we now recognize that Pluto is one of the largest members of the Kuiper Belt. The Kuiper Belt is a large area of space beyond Neptune, containing many icy objects and comets. It is home to numerous Kuiper Belt Objects (KBOs), including some known as dwarf planets such as Eris, Makemake, and Haumea.
This region extends up to about 50 astronomical units (AU) from the Sun and is estimated to have more than 100,000 objects with diameters greater than 100 kilometers. Pluto itself has several moons, with the largest being Charon, and is known for its complex and dynamic surface as revealed by the New Horizons spacecraft.
