The Kuiper Belt and the Oort Cloud are two distinct regions located far beyond Neptune. The Kuiper Belt is home to icy objects, dwarf planets, and comets, while the Oort Cloud is a theoretical spherical shell that surrounds the solar system and is thought to be the source of long-period comets. Both regions contain remnants from the early solar system, providing valuable insight into its formation and evolution.
The Kuiper Belt is known for containing objects like Pluto and Haumea, while the Oort Cloud’s existence has been inferred from the orbits of comets that come from its outer reaches. Studying these distant regions helps astronomers understand the outer boundaries of our solar system and the objects that inhabit them.
