What is the general outward extension range of the Kuiper Belt from the Sun?
Answer
It generally accepted to stretch outward from about 30 AU to about 50 AU.
The Kuiper Belt is described as a sprawling, doughnut-shaped structure whose inner boundary closely follows the orbit of Neptune, starting around 30 Astronomical Units (AU) from the Sun. This region then continues outward, generally accepted by planetary scientists to extend to approximately 50 AU away from the Sun. This vast expanse serves as a deep-freeze storage unit for ancient, primitive solar system materials because the Sun's warmth is significantly diminished at these remote distances.
