The Kuiper Belt is a vast region beyond Neptune, filled with icy bodies, dwarf planets, and comets. It's the origin of many short-period comets and plays a crucial role in the solar system’s formation. Key objects in this region include Pluto, Eris, and Haumea, all of which are considered trans-Neptunian objects.
The belt stretches from 30 to 50 AU from the Sun and is a remnant of the early solar system. Scientists continue to study this region to understand more about the outer reaches of our cosmic neighborhood.
