The Kuiper Belt is a region of the outer solar system that lies beyond the orbit of Neptune, extending from about 30 to 55 astronomical units (AU) from the Sun. It is a region populated by small icy bodies, including dwarf planets such as Pluto, Haumea, Makemake, and Eris, as well as countless smaller objects. The Kuiper Belt is believed to be a remnant of the early solar system and contains valuable clues about its formation and evolution. Scientists study the Kuiper Belt to learn more about the origins of our solar system, the possibility of finding new planets, and the potential for understanding the conditions that led to the formation of life on Earth.
