Part 3/12:
While Pluto was historically considered the outermost planet, our understanding has evolved. It resides within the Kuiper Belt, a region filled with icy bodies beyond Neptune. Beyond this is the Oort Cloud, a vast, spherical shell of icy comets stretching far beyond Pluto’s orbit. Moreover, there are dwarf planets like Eris, Makemake, and Haumea farther out than Pluto, with Eris being about three times farther from the Sun. This means Pluto is no longer the "end" of the solar system, but part of a more complex and extended celestial landscape.
