The Oort Cloud: The Solar System's Shell
What lies at the edge of the Solar System? Far beyond the orbit of Neptune and the Kuiper Belt, deep into interstellar space, we find a vast, thick shell of icy space debris. We have never seen it directly, but we know it exists- because it is the source of the most distant comets that we see entering the Solar System. So why is it there? Today we'll find out.
